I removed my dash and wiring in my race car and need some help connecting to the engine/DME harness though the 14 pin connector. I have the chassis mounted 14pin connector as a tail to splice into.
Can someone help with a wiring diagram or with identifying the wires controlling these items?
Ignition/DME power
Coil Wires

Oh yeah, I need some help with that alternator trigger light that needs installed too.

FYI the dash and chassis wiring weighed 46lbs.

What year DME harness are you using? I assume you are talking about the connector near the fuse panel?

85.5
Yes, connector behind the fuse panel.

See if this helps, put together by TH.

I stripped everything out of the new car as well. I didn't weigh the wiring but it was heavy. What wiring system did you end up going with?

Thanks Tim, thnat should be a big help.

I still need a little help on which leads require power for the ignition circuit to the DME.
86 chassis & it looks like the DME connections are pins 2, 3 & 5.


TIA

This is kind of complicated. Terminal 30 on the DME relay gets power unfused from the battery. 86 on the relay gets power from the key on.. That in turn sends power to pin 35 and 18 on the DME. Pin 2 is idle switch, 3 is WOT switch, 5 is a shield ground. Pin 1 is coil ground to fire the coil. Hope this helps.

Thanks, but I have eliminated the DME relay and want to power the DME directly.
I made the coil ground connection already at the 14pin connector.
The DME connections should all get their signal through the harness back to the 14 pin connector.
So I think I just need to figure out what I need to power, via dash ignition switch, on the chassis side of the 14 pin connector to power the DME.

Thanks

18 and 35 will power up the DME
