cruiser54 Posted March 4, 2014 Share Posted March 4, 2014 No I don't as I did my first one last week. Here we go, I guess. C101 connector elimination Unbolt the 2 halves of the C101. On each half there is a plastic cover where the wires enter. They are removable but you'll probably end up busting them off. Lightly bolt the C101 back together. Peel back the split-loom covering from the body side of the C101 connector down to where the harness splits and goes toward the firewall, pretty much below the MAP sensor. . On the engine side, remove the split loom about the same distance. See first photo. Now you can see from one side of the C101 to the other. Beginning at the top row, closest to the motor, be absolutely sure you cut the matching wires on each side of the connector off to about 1/2 inch. ONE AT A TIME.The wires may be wound a bit in their looms. See the first photo. Get them unwound neatly and do the following, ONE AT A TIME. Slide your shrink tube over one wire. Solder the wires together and then heat the shrink tubing over the solder joint. Keep going until you've done all 22 or so of them. You will find a brown with white tracer on each side of the C101. Although there is only one wire going into each side of the C101, further down each wire going away from the C101, you will find that there is a 3-wire crimp on each one if you've split the loom covering back far enough. See the second photo. What you want to do here is cut the crimp out of each set of three and bring both sets of three wires together and solder them together. All 6 wires. . These particular wires will not end up in your normal C101 elimination loom. See the last photo. After all the soldering and shrink tubing is done, bundle the wires together in a new piece of 3/4" split loom. Tape it up and secure it to either the old C101's bolt hole and/or anything else along the firewall. Third photo.

cruiser54 Posted March 4, 2014 Share Posted March 4, 2014 Know how to post photos on here? Cruiser so you have by any chance have a write up on this c101 bypass? Well $#!&, I guess I have a first draft now!!!! Hornbrod has the photos and I'm sure he'll post them first chance he gets. Someone has to be a guinea pig and do the project, using these instructions and making any suggestions that would be helpful, so that this becomes a "Tip".

88-mj-petersen Posted March 4, 2014 Author Share Posted March 4, 2014 I might be doing it this weekend. So what do i do with the two brown wires with white stripes that go to the 3 wire crimps? Link to comment Share on other sites More sharing options...

cruiser54 Posted March 4, 2014 Share Posted March 4, 2014 I want you to use the instructions and then let me know, good or bad. Link to comment Share on other sites More sharing options...
88whitemanche Posted March 4, 2014 Share Posted March 4, 2014 So on each side of the c101 every wire that are the same color on each side of the connector correct? Link to comment Share on other sites More sharing options...
cruiser54 Posted March 4, 2014 Share Posted March 4, 2014 So on each side of the c101 every wire that are the same color on each side of the connector correct? Pretty much. But the wires may be faded, slightly different colors. Use location, one by one! And, keep an eye on Post 27. Me and Hornbrod are updating it almost daily.

metrictonner Posted March 7, 2014 Share Posted March 7, 2014 Mine started doing the 2000 rpm thing after I changed the air filter a few months ago. I've been trying to hunt down the problem too although I noticed I now have no lifter ticking anymore, hot or cold, so I'm really not interested in doing anything until my oil pressure starts suffering. The thing is the computer is sending a default signal to the IAS for some reason. A simple check with a RENIX diagnosis thingie would probably pinpoint the problem. The default could be due to a bad MAP (vacuum), bad MAT (temperature), bad TPS (pre-vacuum guess), or a bad IAS (closed throttle plate bypass). And as the Renix manual states: not only check the sensor but check the connections too. Too much when a simple diagnosis meter will tell all. Renix also says the the meter is used to set the TPS properly too, no matter what formula you may use. Link to comment Share on other sites More sharing options...

88-mj-petersen Posted March 8, 2014 Author Share Posted March 8, 2014 Just got done with the c101 elimination and it went pretty smooth following your directions. Started and everything seems ok but i havnt had a chance to test drive it and get it up to temp yet because i have to finish a few things. One question tho. I have 4 extra wire that were on the c101 3 on the engine side and one on the firewall side. But the don't go to anything. Should they have wires going to them or is it possibly because i have a manual tranny and no cruise and what not? Link to comment Share on other sites More sharing options...
88-mj-petersen Posted March 8, 2014 Author Share Posted March 8, 2014 Well c101 elimination went very well. I didnt kno what to do with them extra wires i had so i just cut and taped them. But it still idled to 2000 at start up and went right back down again. Had a great idle cold( about 800rpm it was at about 900 to 1000 befor)and everything seemed perfect until it started to warm up. seems to idle fine until i drive it warm. Still idles at 1500 warm. I checked the tps(0.80v) and i double checked sensor grounds after i was done. Do i maybe have to reset the tps again? Otherwise I'm think something like the map sensor or o2 sensor. Mabe i should triple check the grounds i cleaned as well. Or maybe theres other grounds i didnt clean up? I started to notice a little missfire at idle earlier this week. Could the fuel pump cause a high idle? Link to comment Share on other sites More sharing options...

cruiser54 Posted March 8, 2014 Share Posted March 8, 2014 What color are those wires? Do the sensor ground test again. Link to comment Share on other sites More sharing options...
88-mj-petersen Posted March 13, 2014 Author Share Posted March 13, 2014 Looks like a black and yellow wire on the firewall side that runs into the c101 but not out and a orange, gray/black, and red on the engine side that do the same thing. Go onto the c101 but don't come out the other side Link to comment Share on other sites More sharing options...

cruiser54 Posted March 13, 2014 Share Posted March 13, 2014 I've only done the C101 elimination on auto trans rigs. Maybe that's it. I don't feel like reading wiring diagrams right now. LOL. Link to comment Share on other sites More sharing options...
