Alright, I've been searching for about two hours now and have figured out how to do the OBD2 dizzy to OBD1 conversion, I just can't find one thing:

What do I do about the tachometer signal wire that's on the 2-pin plug for the OBD1 dizzy?

What I'm trying to do is wire in an OBD2B distributor to an OBD1 engine harness. Since OBD2B distributors don't have a tachometer signal wire, and the OBD1 distributors do, how do I go about getting that tach signal so the tach on my instrument cluster will work?

If I had an OBD2A dizzy, everything would work out fine since those have the signal wire.

If anyone knows the answer to this, I would appreciate it if you could reply.

Thanks in advance.

 

I have the same problem. Your missing a wire from the tranny that signals the speed, tach, gas, and temp. If your tranny is cable you cannot get it connected. If Its hydro, then you can but its going to cost ya....

 

read into the signal from the CFS crank sensor, i think it has the same signal and can be used, but im not sure. good luck.
