Tach Not Working - Need Wiring Help
Since my winters work in the car my tach seems to have stopped working. I removed the HVAC system along with a lot of other stuff, so the wiringf could have ben disturbed.
On the engine harness into the ECU there is a red modular plug that has 2-3 wires goingf to it. It is not connected to anything. Could this be my problem? Tryaing to work back from the ECU.
TIA, John

Ok, finally working on this. Can you tell me which connection coming out of the ECU is for the tach?
The 1st picture is from the ECU, the second picture is of a connection coming out of the harness behind the tach.

I had the same issue with my 87NA. The plug shown in this pic was the culprit that I cut out by mistake. The white-w/green stripe and green w/black stripe were the wires (coming from the ECU) that make the tach work. I thought I was careful as I hacked wires. I would hack and then make sure the car would crank and then hack some more. When I was done the tack was inop... Between this post and my Haynes wiring diagram I got her fixed up.
Hope this helps somebody

Thank you for this photo of the red plugs !!!
I feel Like Elvis after this -
Again many thanks to the dedicated fans of these cars, I have never been so happy & now ready to go tear it up in a test drive - then i get to:
strip to bare metal, seal, bodywork, prime, bc/cc & get all of the interior & glass out of storage...
Then sell her & do it all over again !!!!! but next time will be a 100% complete resto or maybe a track car !!!!!!!!!!!!
