87 m50 speedo doesn't work and tach doesn't work, whenever built this car (still trying to figure out) hard wires stuff like the lights and what not, and I got 2 tickets for speeding but they got dropped to improper equipment, can someone PLEASE explain on this post how to wire the tach and speedo up with an M50 swap on a early model?!?

PS: I have looked at the other threads about this and I'm not good with wiring at ALL!!!

Look in the glove box for a 3 wire plug. It should have a black wire, white and yellow wire, and a green and red if I can remember right. The black wire needs to be sent to pin 14 on the x20.

That will get your tach working.
