New guy, need some wiring/engine help.

[Demi_II]

Hey guys. I've got a 87 BII 4x4 manual trans, and I have been trying to restore this thing to its former glory. I hate to be the new guy that turns up with problems day one, but im in a spot, and I hoping you guys can help. Sooo....

I swapped in a new motor (still a 2.9), extended the engine bay harness and ran it along the fram so it wouldnt be running through the plenum. That all went well. I pulled the dash and the wiring harness, and that is where the troubles started. As soon as I got the dash back together and the wiring harness in, and pressed the clutch, the horn went off. And now it blows constantly, so I unhooked it until I could find the problem. No cluster lights. I have the rear ABS light on. It turns off when the truck is started and then comes right back on. Lastly the engine starts sputtering and backfiring when it revs higher than 2500, with and without load. Ive set the timing at idle, and its at 8-10 BTDC. My thinking is something didnt get hooked up, or something was hooked up wrong and/or I jerked some wires loose. I used to be an aircraft electrician, before my current military job, but civilian wiring systems and military are waaaaaay different. lol. So I suppose one crisis at a time, can someone ID this wire?

The wire in my hand is the same one in the plug. Wire color are yellow/red,black/white, and what looks to be blue/green.


Sorry for the problem bomb on the first post. Many thanks ahead of time.

reads like something is crossed
higher rev stalling could be no timing change or low fuel pressure, might even be a TPS issue(throttle position sensor)

Have a look here these are the electrical diagrams with color codes, could be helpful

Black is usually a ground but not always

reads like horn wire from steering column got shorted from clutch linkage, pinched.
There is a Clutch safety switch(NSS) on the pedal arm but wiring would have to be very screwed up for that to set off the horn.

Thank you for the reply. Its hard to tell because the wire is old but it looks to be dark blue and green. I was hoping someone could look at the plug and just see where it goes, im having a hard time finding it in the wiring diagrams as none of them ID the connectors. Its part of the mess of connectors on the aft driverside of the engine compartment. I also cant seem to find the wiring diagram for the horn. Im hoping to ID several wires that run through a single connector that may not be hooked up or seveal wires that may be pulled out. Im just taking it one step at a time. Can someone look at the connector and see where that goes for me, or point me to where it is on the diagram?
