Sup all, installing a 52mm tach in a friends car and I need to know which wire do I tap into for the RPMs??

I already got the ground and power but now I just need the signal on the distributor or cluster to tell me the RPM's.

Thanks!!

 

check the computer diagram for rpm sensor.

 

what a shitty post...

It would help if you supplied year/make/model.

 

Well as far as diagram for cluster i have no idea, but i can give you the easy choice wire.

Tap into the blue wire with connector at the shock tower on drivers side. There is 1 plug with 1 wire. Thats the one HONDA uses to check rpm idle etc. You cant miss is. Its the only one plug covered in some sort of boot. By the clutch reservoir.

 

first i agree. go to bulldogsecurity.com and look up the car in the wireing diagrams then look for tach signal on the instructions remote starters use a tach signal also

 

Ahh yes I know that plug!

In case anyone wants to know, I just rubbed the wire across the cluster harness plugs till the tach 'moved', then I soldered it to that one. It works like a CHAMP.
