Injector signal wire

[scotts99snake]

I am installing a dynojet wideband commander in my cobra and need to know which wire is the injector signal wire. Anybody know? Thanks.

For RPM Scott? Could do it this way, not sure if you want to take the cluster out though..

Thanks for the reply Dave. I called my buddy Rob. He said all the injectors will have a common colored wire. The other one will be the signal. That is the way I hooked it up. Not 100% sure whether it is right or not seeing as though I haven't tried to datalog, but the wideband seems to be working fine.
