Gack. Sorry for the double post.

I've got a 73 142 with a rotten harness.

You can buy a new wireing harness for an 1800e from CVI.

Would this cvi 1800e harness work for a 142? My main
interest is replacing the FI wiring. My main concern is
that the 73 has the newer gauge cluster so who knows what
other stuff changed between them.
thx,
chris

Hi Chris,

The FI harness in my 122 started out as one from a 140 and I just put one in from a 1800 to move the ECU under the dash. That will be your first potential issue; the shorter trunk into the cabin.

The 140 harness had several connectors that the 1800 part lacked as well. There was an unnumbered yellow wire that came out at the firewall and was tied back into the harness near the MAP sensor, I think. The early 1800s have a relay for the cold start switch. Everything else has the thermal timer gizmo. The 1800 harness also did not have the wire that connects to teh negative terminal of the coil. None of these were real issues and just meant I had to look at page 78 in the Haynes manual.

The D-jet harness is completely discrete and the model year of the car should have no implication in the chassis electrical side of things at all.

Anyway, hope that makes sense. The only real issue you may have is the location. You could just put the ECU in the glovebox, though.
