    Decided to tackle the relay job today.

    FWIW, the later style vacuum/relay combo pictured here does not really work on a modified early fender liner. The relay holder is too "deep" since the area is flat. No idea if the '90/'91s are any better, but the early side mount vacuum/relay combo is preferred.


    Fuel pump relay wiring was the worst as far as insulation recession went. The yellow lead could be yanked straight out of the block.


    Factory ground splice, IIRC. Whatever fabric based taped that was used crumbled off when I removed the wires from the harness. Re-wrapped with electrical tape.


    All wiring exposed with relays hanging.


    Updated relay holder installed with EEC diode. This was going to be a solder and heatshrink job, but the ancient (and cheap) iron called it quits after I did one lead. Since I had already cut the EEC relay 100% out, I was committed, so butt splices with heatshrink were used instead.


    Stuff "tidied" away. The holder doesn't sit just right since it's a new style holder on an old style vacuum box. I'll see if I can find a side mount holder next time I'm at the yard so it'll sit nicely. At least it's latched into place.


    I had to extend two leads out, one for the EEC connector from a leg on the fuel pump relay, and another for the A/C Diode lead from a leg on the A/C cut-out relay. Beyond that, I was able to shorten up most of the wires by about a foot and adjust the looming to fit.

    Here's a note card of all the pinout/wire colors I used.


    FWIW, the EEC relay wiring did not 100% match my service manual. The 12v+ Constant BK/O wire was just Black and the Ground BK/LG either originally was green and faded, or it was using black with light blue striping. All the other wires matched respectively.

    your handwriting is entirely too legible for a working note card. My scrawl of notes when I'm putting stuff together may as well be in hieroglyphs.


    Honestly that wiring is in better shape than many are. Nothing there makes me go "aha" though. I wonder if one of the relays was failing mechanically. If the return spring breaks, you'll get stuff randomly engaging if it gets moved around.

    I guess that is why the later harnesses use a similar splice, but embedded in marine type heat shrink. The stuff with the glue in it that oozes out and seals things when its heated. I had to cut a few of those out when I did the cornering lamp retrofit on my '96, I couldn't find in-tact '95-'97 GMQ side marker harnesses that had cornering lights so I modified ones from a '94 instead (basically deleted the extra bulb and wiring for the turn signals, but also integrated the "blinker mod" since it was cut up anyway). I cut one of those factory splices apart out of curiosity and the splice its self looked pretty much the same as that one, but it was in heat shrink rather than wrapped in tape. FWIW, my splices were done similarly, soldered and marine heat shrink, because IMO that is the only way to do splices under the hood if you expect them to last.

    the later harnesses were sealed up better. The tape wrapped blob splices were typical through the 80s at least. The connectors are also not sealed other than with whatever terminal grease that may have been packed in there.

    Here's a dumb thing I've never checked for:





    Tethered gas cap. Saw it on the junkyard '87 and took it. I've had a replacement Stant unit since I got it, and it clearly had been around for a while. Just a bit curious how frequently those pop up, or if anyone else has one and I've just been the sucker dealing with a basic cap.

    I think I have a couple of good tethered ones in my spare parts. In some States checking the gas cap is part of the smog inspection. Gas caps fail allot. The tethered ones get in the way of the gas nozzle.
    I have locking gas caps on everything.

    The tethers commonly break. The 90s models had a single cord to the top center of the cap rather than the "hinge" thing that the 80s cars got. Those seem to hold up better, and they fit boxes fine. The one on my car is from a mid 90s Escort. The original was broken when I got the car.

    The one like you installed is what the Mad Marquis came with. The strap never broke. I did have to replace it though because the cap failed. The single plastic string on the 93 though... that one broke... and then the cap failed. So it's got a new one as well. Though that was several years ago now.

    Interesting, my '89 has the single string type (broken string). I wonder if it's not original if the 80s ones usually came with that strap set up.

    Ive seen a few of them still around in the junkyards but they disintegrated when I went to flex them. I did want to get it.

    I have been using a locking style since forever. I also do not want a cap rubbing against the paint. If a tethered option was available combined with a neato holder for the removed gas cap while filling up I would be compelled. I just place gas cap on top up gas pump during fill ups.

    So I grabbed a few more things from that '87 at the junkyard. I thought I could get an un-seized door lock actuator from a rear door out, but I couldn't figure out that setup way up there in the door. I did notice that car seemed to be riding the line between '87 and '88 parts. I took it's weather barrier, and it was a nicer plastic E8 branded one. Car was a 07/87 car. Might explain why it has the later style air vents that seems more in line with the '88-'89 cars.

    Anyway, I've started swapping the air vents over to replace my floppy early style ones. The later ones look nicer and do feel more sturdy compare to early ones. I'll update with some pictures later.

    I also grabbed the ECU from that car, simply because I figured it wouldn't hurt to have a spare. Any magic I should be aware about these SEFI ECUs? This one is branded with a catch code "DU" and a series "SFI-SD1". P/N E7SF-12A650-U1A.

    Good question about the ECM. I've always wondered if one year had a better tune compared to the others or if they're all the same. I've pondered the same about GM vehicles.

    Only real difference (functionally speaking) in the ECUs for speed density cars 86-91 is the 88-91 have cruise built in and not in a separate module.

    yeah, basically that. Related to that, the late ones need a VSS input, the early ones do not. No VSS input on a late ECM makes the EGR valve open at stupid times and you'll get a nasty off-idle hesitation.

    Here's a dumb question: Lets say a capacitor has begun to fail on a board, but not fully failed, is it possible that the drive cycle memory may be affected? I only ask since I've noticed if the car sits for several hours, when fired up it runs like it just had the battery reconnected. It has to figure out its idle every time. Sometimes it'll stumble on the initial take off, then never do it again until it sits for a while. I've noticed it usually would run better throughout the day if several short stops were made where the engine was off for less than 30 minutes, then restarted.

    I figure it's equipped with the original computer. I doubt the capacitors were designed with 32 years of operation in mind, especially in a hot and humid climate, based on what I've read. I'm going to inspect the ones from the salvage yard, and possible change those out. I'd like to see how the factory ECU looks inside.

    More likely the ECM may be having an issue driving the IAC. But there's only one large capacitor in the ECM (at least the one for the 88 I had) so it wouldn't be that hard to check after taking the lid off the ECM.

    As for how it looks inside... Here's the pics of when mine released the magic smoke. The cap puked and lit it up.

    Oh wow, that's some shit stain!

    Did the car still run? Was that ECM salvageable/repairable?

    Nope. Had to replace it. The PCB burned all the way through. All of that blackened area was complete toast.

    I wrestled the ECU out of the '87. It really didn't want to come out.

    This one is stamped RM, has the gasket number blacked out, and someone wrote a number on the other side. I suspect all that points to this ECU having been a remanned unit. Carries otherwise factory Ford stampings and warranty sticker, so no idea if it's a Ford remanned unit.



    FWIW, the capacitor towards the rear of the board is leaking out on one of the legs.

    I haven't been able to open up the LTD one yet since I used a socket that was a bit worn and nicked one of the screw heads on the upper portion, and my good socket doesn't get all the way down to the base, so it just slips on the nicked portion. The rest came out fine. I want to inspect that one for any additional revision markings inside.
