    Borg Warner electric synchronizer power?

    On the K3500 with BW transfer, there is a red wire that powers the synchronizer in the transfer case. This power wire comes from a 4x4 relay under the hood, that only one ton Borg Warner trucks have (my understanding). Is this supposed to be powered while in 2wd or 4wd. A GM service book states...

    1997 lever 4x4 k3500 4wd wiring schematic

    Yeah, I didn't really know or find a perfect section to put this....it was under the hood technically.... This 97 doesn't "appear" to have had the updated wiring installed, it looks more original to me, but used. The wiring going to the relay looks original, but based on how a relay works, I...

    1997 lever 4x4 k3500 4wd wiring schematic

    Thank you...I'll look into it. I had assumed this 1997 was new enough that it originally came with the better actuator from the factory. Maybe someone wired this relay incorrectly? Because the way I understand it, this relay is shorted to ground, based on the schematic, and the way my truck is...

    1997 lever 4x4 k3500 4wd wiring schematic

    Doing a little homework...my truck relay under the hood for 4x4 is wired just like this GM diagram. Nothing online I find shows the ground to be placed in this position. This has me thinking the truck relay is wired wrong........?

    1997 lever 4x4 k3500 4wd wiring schematic

    Hi all. Looking for 1997 k3500 automatic with floor lever transfer case schematic. I am blowing 4x4 fuse even with actuator unhooked. I have replaced transfer case switch already. It won't blow fuse with the 4x4 relay unhooked under the hood. On a side note, this appears to have a red wire...

    No speedometer until installing driveshaft.

    Working on an auto 1997 k3500. After installing 2000 7.4l engine, and rebuilt tranny with a 1996 engine harness, I didn't have speedometer working. I assumed it was a wiring issue from the new 7.4 and 1996 wiring. I would put the truck in gear, with no rear driveshaft, and the speedo didn't...

    1996 C100 wiring harness connector not matching 1997 C100 firewall

    The tachometer pins don't match from the 96 to 97 truck. I relocated it to the e8 position on the engine harness side and now it works. The alternator wasn't working because its exciter pin actually got bent over from the last time the c100 connector was attached. There are a few other pins that...

    1996 C100 wiring harness connector not matching 1997 C100 firewall

    Thank you very much. I never made it to page 9 in that thread. Yes, I found the c100 schematic on Book 2, 8A-202-0. And, on paper, it does appear to be different than the later years c100 schematic. Now, I have on paper some info to look at, while re-pinning the harness. THANK YOU!

    1996 C100 wiring harness connector not matching 1997 C100 firewall

    I am working on a 1997 k3500 auto 4x4. It had a bad 5.7, so I installed a 7.4l. I used the wiring harness from a 1996 k3500 7.4l 4x4 auto. The engine and tranny work well, but a few things aren't working, and it seems the c100 firewall connector are not the same from this 1996 wiring donor...
