I'm actually trying to troubleshoot a problem with my CTS .. Correct me if im wrong.. The CTS connects to C25 of the pcm.. but where do u pickup the output for the gauge? I think i may have just hooked the CTS wire to the gauge and the coputer doesn't see the temp.. just wanna check this out.

 

There are 3 connectors, the wires should have a grommet on them, those are the connectors for the I/P. One's blue, and one's tan I think. I'm sure someone will chime in with more detailed info.

 

yeah i have the pics for them.. however since this is a swap those connectors are history.. i show C25 as ECT (Engine Coolent Temp) sensor signal.. is this the same as the CTS? i assume so.. and that would put it near sparkplug #1 & 3 .. is so.. where do u wire up the temp gauge?

better yet.. C220 shows pin K (dk grn) as CTS feed to cluster.. circuit 135. where does this come from?


thanks

 

got er fixed.. i am 2nd guessing myself.. trying to find out why it is lean..
