88mjblue Posted April 10, 2015 Share Posted April 10, 2015 So I lost track of the wires while doing Cruiser's c101 delete... and now there are some wires that don't match up. How do I check this? Are all years the same color scheme? Does anybody have a picture of the c101 that shows which wire goes where to which color? Also, how many wires/connections should there be? I already did the sensor grounds so that should be 1 less connection, right? Help! How would I check if I made all the right connections? Link to comment Share on other sites More sharing options...
Eagle Posted April 10, 2015 Share Posted April 10, 2015 Somebody very recently posted a link to the 1988 electrical manual on-line. Link to comment Share on other sites More sharing options...
88mjblue Posted April 11, 2015 Author Share Posted April 11, 2015 Ok, I'll take a look at that, do you know if it has a color legend? I'm so close, just a few wires that don't line up. Update: I removed 3 wires that went to an unplugged connection (for auto transmission) and just removed that, so I don't have to worry about those wires. That's okay to do, right?

Megadan Posted April 11, 2015 Share Posted April 11, 2015 If they were for the TPS plug for the auto trans, shouldn't cause a problem. That plug normally hangs in the breeze doing nothing anyway.If you can't find anything by the time I get off of work, post up a picture of the wires you have left and I can compare them to my wiring harness and try to lend a hand. I did the C101 delete a few months ago. Link to comment Share on other sites More sharing options...
88mjblue Posted April 11, 2015 Author Share Posted April 11, 2015 (edited) Update: I have narrowed it down to 2 wires that I need to differentiate between. Both tan wires, one is the #3 fuel injector, the other is the coolant temp sensor. How can I tell which one is which that comes out of the ECU? Also, I have a remaining wire coming out of the firewall side that doesn't have a wire to connect to. It is blue with a white tracer, what could that be? Edit: According to a wiring diagram I have, that blue + tracer wire could be the "A/C Clutch relay" - and since I don't have AC, that could explain this last missing wire. Does that sound familiar to anyone who has ac, something going through the c101 connector for a/c? I checked the electrical manual, but it shows the ac clutch relay going through c104...

88mjblue Posted April 11, 2015 Author Share Posted April 11, 2015 So I found this: What is the method for testing wires? I haven't done much electrical work, I do have a digital multimeter, but can't figure out how to do this... Link to comment Share on other sites More sharing options...
Eagle Posted April 11, 2015 Share Posted April 11, 2015 Where's the diagram for the C101? Link to comment Share on other sites More sharing options...
cruiser54 Posted April 11, 2015 Share Posted April 11, 2015 Can you give us the letter and number designation of the position of the wires at least on one side of the connector? Link to comment Share on other sites More sharing options...
cruiser54 Posted April 11, 2015 Share Posted April 11, 2015 Injector #3 goes into E3 on the c101. CTS goes into B1 on the c101. Link to comment Share on other sites More sharing options...
88mjblue Posted April 11, 2015 Author Share Posted April 11, 2015 Thanks, I got everything sorted out - I took the ECU down and checked the wires with my DMM on continuity, sorted out which tan wire was the fuel injector, then back tracked the tan wire that came from the #3 fuel injector. The other was the coolant temp sensor. Fired right up and running fine! One thing I did find was that the mysterious blue with white tracer wire was NOT the ac clutch relay, but instead came from D6 of the ECU, which is blank as you can see from Cruiser's picture I posted earlier... What do you make of that? Final product: Link to comment Share on other sites More sharing options...
cruiser54 Posted April 11, 2015 Share Posted April 11, 2015 Wait. I'm really confused here.... You said you weren't good at electrical? What a job!!! Link to comment Share on other sites More sharing options...
88mjblue Posted April 11, 2015 Author Share Posted April 11, 2015 I was forced to learn a few things in the process :). Overall, a great learning experience for me. I learned a lot about the wiring of the engine, as well as soldering, and using the multimeter. I'm still curious about that one wire though, I just taped it up and tucked it away.

cruiser54 Posted April 12, 2015 Share Posted April 12, 2015 You had to stretch a bit and get out of your comfort zone. Good for you. As for that wire......Bzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzt Link to comment Share on other sites More sharing options...
Eagle Posted April 12, 2015 Share Posted April 12, 2015 Wait. I'm really confused here.... You said you weren't good at electrical? What a job!!! 10-4! That's a VERY neat job. Link to comment Share on other sites More sharing options...

88mjblue Posted April 12, 2015 Author Share Posted April 12, 2015 Thanks, I kind of freaked out a bit when I got to this stage and realized the wires weren't matching up: I know Cruiser specifically says to go one-by-one to prevent this, but I was originally trying to do this: http://comancheclub.com/topic/43187-addendum-to-cruzer54s-c101-elimination-deletes-connectors-but-retains-connector-housing-for-orginal-look/ and after checking about 10 wires in a row all matched up before I cut, I decided it was going to be easier to cut them all out first and then solder them up back into the connector. But, that plan failed because my C101 was so "tarred-up" and I didn't have the tools to properly hollow out the connector. In the end it was for the better because I got rid of the x3 auto trans TPS wires (and that mystery wire) and knew exactly which wires I was connecting and where they all came from throughout the engine compartment.
