ok i just swapped in a b series in my eg and now my tach doesnt work, but i noticed that on the plug that goes to the distributor it is blank where the big blue wire goes. so i want to know if i can hook a wire from the blue wire on the distributor to the single blue wire on the drivers side shock tower to make the tach work?

try and see...if it comes on it works,,,,if it don't.....doesn't work.

 

I usually just splice an aftermarket tach in there when dealing with a car with no tach.

 

well i wanted my factory tach working, i dont like does big aftermarket ones.

 

If all else fails, just run it to your ecu.

 

anyone know which wire is the tach wire by the passenger side shock tower or which wire by the ecu?

 

you should just be able to run a new wire, i had to when i got my msd 6al box because my tach went nuts

 

there is 2 black and yellow wire. one connect to the module and then the coil. this will be your positive. your negative will hook up to the - of the coil

short and easy answer. yes.

This is a typical problem when using some ODB2 engine harnesses and an OBD1 chassis harness. (some OBD2 engines received the tach signal to drive the tach from the ECU not the distributor)
