i searched alot of different combinations and cant find anything, i bought a raptor shift light and know where to hook power and ground but i dont know where to run the tach wire to.

its a 1989 crx si obd0 with a zc and it says i should run it off the ecu, it says i should not hook it straight to the coil as it wont read right.

can anyone tell me what color the tach wire of the ecu is or can i use a splice connecter on the negative wire off the distributor?

any help would be greatly appreciated.

 

Blue wire

is there only one blue wire off the ecu?

 

not off the ecu its behind the gauge cluster and that one i believe runs off the dizzy not sure but thats the one i used for my d15b but it might not work due to the fact you have a zc
