Alright, alright! I had to get the E92 as a transition from Jeeps and a Denali to a boosted E28.

Update: Finished modifying the M5 engine harness to the aftermarket sensors. Added an ARC fuse panel. Still some issues with the E24 fuse box swap. Seems the diagram I was using isn't entirely correct. Pulled the car onto a flat bed a week ago and has been at Turbo Lab getting sorted and a base tune to break in the motor. Funny how much smaller the E28 feels than the E92. Even with all the extra crap on the E28 it's still ~300 lbs lighter than the newer car.

Need a wiring harness to complete this project. Have a modified M5 engine wiring harness and an E24 fuse box. During the conversion from the OE torpedo fuse box I failed to scratch out several circuits on the board. Hooked everything up and had a melt down. Rather than trace through and repair the wiring it would be much easier to replace the fuse box to dash wiring harness.

Can anyone confirm the part number of the harness in question? Or, does anyone have a used harness they'd be willing to sell?

Main wiring harness

No. Description Supp. Qty From Up To Part Number Price Notes
01 Wiring harness, front section 1 09/1985 61111380250 $308.49 ENDED
02 Cable harness sector ctr. 1 09/1985 61111380206 $603.06 ENDED
03 Cable harness sector rear 1 09/1985 61111375788 $558.92 ENDED

:shock:

If you haven't already, put a post in the FS forum. There's a few people that still either have parts cars or part them out. Hopefully they can get you taken care of. That is going to be a less-than-fun job. Just make sure you get a harness later than 9/85.

Good call Chris. Which circuits in this harness are different in the pre-9/85 models?

Any idea which part number I need? There's may be a chance there's one out there though listed NLA.

Thanks

Is the harness in question ///M specific?

No. The harness is not 'M' specific. The engine wiring harness is from an 'M' and was customized by AEM for their ECU. The harness I need would be from a post-9/85 M30 equipped E28 extending from at least the fuse box back to the drivers firewall or the battery to the cluster even.

Thanks. With the OE parts NLA and no one making an aftermarket kit I'm in need of a 9/85+ harness, not 'M' specific but extending from the fuse box through the firewall (see photo above).

Hey Mike did you ever get the wiring harness you needed? Looking forward to further updates.

Yes. Miraculously the harness was found and the project continues. All electrical is working aside from the idiot light panel between the visors due to removing the OE ECU. The E24 fuse box was FUBAR. The documentation I had was incorrect. Also, the M5 engine harness required several circuits to be scratched out. Because this wasn't done several of the finer gauge wires melted.

Dealing with some AEM-specific issues now. The car fires and runs but working through some misfires. Once this is sorted and the motor broken in we'll proceed with a full tune on the dyno. Was attempting to hit the road last fall.
