onlyinajeep726 Posted September 25, 2013 Share Posted September 25, 2013 Anyone have any tips or write-ups on removing the AW4 TCM harness from the main engine harness for a '90 Renix 4.0? Since I've got it bolted to a AX15, I know that jumping the pins for the NSS is necessary for starting the engine, but I don't want unnecessary plugs/harness all under the hood. Any help would be greatly appreciated! Link to comment Share on other sites More sharing options...

carnuck Posted September 30, 2013 Share Posted September 30, 2013 I swapped mine out to put in the AW4 (90 harness with no C101 connector problem child) Link to comment Share on other sites More sharing options...

jimoshel Posted September 30, 2013 Share Posted September 30, 2013 Mount a switch under the seat, under the dash, some inconspicous incunspicous, unobvious unnoticeable place. Instead of jumping the plug run two wires to the switch. Have to flip the switch, or use a push button to start the engine. Sort of an anti theft device. Wish I could find out what happened to my dictionary. LOL Link to comment Share on other sites More sharing options...

JeepcoMJ Posted October 1, 2013 Share Posted October 1, 2013 You don't need to Just remove the TCM, or the fuse for it, then cut the NSS harness off of the switch itself, and wire that to your ax15's NSS and reverse light plugs and call it a day. keeps it looking factory. The engine harness for an ax15 still has the extra TCM plug for the TPS anyways, it's just not used. Link to comment Share on other sites More sharing options...

(Which my '86 doesn't have one of those either). Link to comment Share on other sites More sharing options...

No manual has a NSS thats an auto thing and I beleive no MJs have a clutch safety switch either (my 92 doesnt and I think it was 97 they started having them) Link to comment Share on other sites More sharing options...
JeepcoMJ Posted October 2, 2013 Share Posted October 2, 2013 My apologies, it's been awhile since I've messed with them. Either way, just cut the AW4 NSS wire off the switch, loop B and C for NSS bypass, tie in reverse light switch off ax15, call it a day. Link to comment Share on other sites More sharing options...
carnuck Posted October 2, 2013 Share Posted October 2, 2013 My '87 had the clutch safety switch. First wiring "fix" I did when I got the truck was bypass that. (my slave cylinder had gone out and I was synchro driving to and from work in Bellevue, WA till I remembered my Uncle Red telling me that Crisco cooking oil or similar was thicker and didn't leak. I filled it only 3 times then didn't need to do it again until after the pilot bearing seized itself to the trans input shaft making my truck jump forward and nearly plow into the new Mercedes that was in front of me. That said, $60 gets the known good Renix engine harness for manual trans delivered in the US (complete up to the C101 connector) Not sure where I put the other part but I plan to make a quick connect for HO wiring swap from it.

Thanks, but I'm not in need of the harness. I have everything already ran and installed for my particular application with exception of the aforementioned backup light switch. But perhaps someone else may need this. Link to comment Share on other sites More sharing options...

onlyinajeep726 Posted October 2, 2013 Author Share Posted October 2, 2013 So do I wire pins A and E to my back up light switch to get the reverse lights to come on? I know that sounds like a stupid question, but I want to make sure so I don't fry my ECU. Link to comment Share on other sites More sharing options...
