Got 1993 Honda prelude si with a h23a1. Getting ready to install a aem f/ic and it is asking for a cam signal to hack at the ecu side. Im not sure witch wire I'm looking for, is it "cylinder position signal" or "top dead center" or neither? I'm am thinking its a mag type sensor pickup? just need to know what Honda is calling the cam signal so I get the correct wire I'm looking for?

 

Cam Signal would be the CYP found in the distributor. It is a 2 wire Mag style sensor, they are the ORG & WHT wires. The ECU pins are B11 (CYP-P) & B12 (CYP-M).

 

see what i mean? posting your question in the right area always helps to find the person / people that have the answer you are looking for.

 

Thanks , works great!
