Wiring question

[5l32v4c]

Question about the fuel injector wiring harness on my '85. It comes out of the firewall into the engine compartment on the passenger side (car is left hand drive) underneath the coolant expansion tank and goes along the back of the engine. The first bunch of wires that break out of the main harness are 5 or 6 wires that come together in 2 eyelet connectors, presumably to go to ground somewhere, but I am not sure where.

A few inches further on, there is a single wire that breaks out of the same harness that goes to ground on a bracket retaining bolt on the firewall, but these first two sets of wires are about an inch short of reaching that point.

There's a lot of stuff underneath the expansion tank so it could just be that my harness has got wrapped around something and has lost some length and these two eyelets should attach to the aforementioned bracket bolt. Just need to know where to attach these two eyelet connectors. I can post a picture if that would help.

Here's a picture;

Not sure where they go exactly, but they look like grounds to me...possibly on the cam cover somewhere.

Been out of pocket for a while on another project - a friend's nice 87 928 was hit at a red light and we've been trying to sort out a running battle with his insurance company. Of course they want to total it out and basically give him what he spent on his tires. I'm sure the insurance adjusters are only doing what they are being told but - Mercy What a Crock !

Hey 4c - I agree with Airtek - It appears that the wires you have pictured are the ground connections that go between the engine block and the fuel and ignition computers. Both the wiring terminal lugs should easily reach a couple of small bolts along the right cam cover.

To avoid all kinds of hard starting and/or intermittent run problems.... make sure to inspect all your primary ground connections 1) the main negative battery cable to the rear hatch chassis contact point 2) the main short jumper cable between the lower right side of the engine block and the chassis contact point 3) the brown harness wires (you found) between the fuel/ignition computers to both the firewall and the right hand cam cover AND 4) all the chassis ground contact points just above the passenger foot well fuse/relay panel.

Good Luck, Michael

Thanks guys. Cannot find anywhere to ground within reach of these wires so will make a small bracket. I suspect my harness got re-routed and lost a bit of reach at some point.

those grounds get connected to the bracket at the back of V in the block under the fuel regulator and FPR

Thanks Mrmerlin to the rescue - Hey 4c - He's one of our 928 encyclopedic resident specialists. If he doesn't know about something - no one does.
