Looks to be the exact same as as the 03-05 plug, but the change in color from red to green.

Sucks...I could saved you $20, if I knew.

I cut the ECM plugs off an Astro at the junkyard, so I have a ton of pins attached to a few inches of wire. (Still in plug) I can harvest a few pins and mail them to you, if you want, or a whole plug, so you can see how it comes apart before you you start. They’re plugs from a 2003-2005, though. Not...

Thanks captn' crunch and racr7x. I'll probably post another video once I get my 4lo done. I can help with with connecting to the ECM, if you need it, but not sure what year you have. I drilled a small hole in the firewall behind the battery…3/32 bit, I think. Then,I shrinked wrapped the section of ...

Nice work!!!

It was the switch!!! I didn’t test resistance at Nuetral on the switch I tested, and molded i to my dash pre-maturely. (holding 2Hi and 4Lo) That’s why I couldn’t find the hiccup. I was aboit to pull my hair out. I was questioning whether I made the right choice to use a 236 instead of a 233, but no...

Alright…so I wired in a switch from a 99- Blazer that has the same blue plugs that the switch racrx7 used. Lights all came on, and 2Hi was lit. Auto AWD stayed lit. No 4Hi But, when I push Auto AWD, and the trans is in Neutral, it switches to 4LO and back out when I push AWD, again. I wired it just ...

So...That didn’t work, but I can now hear signals being sent to the TCCM when I push buttons on the switch. I used a fuse tap at fuse 15 under the dash instead splicing into E10 a second time. (1st time for relay) Would that cause any issues? Another quesrion...could a shop with a scanner read this ...

I think I figured out my mistake when I was gearing up to change the switch to the type Rinny used that’s wired like the one racrx7 used... I think this: G - Switch Illumination wire fed from fuse 12 is supposed to be fed from fuse 15! Will update when I’m able to test, and will confirm wiring the v...

Hey folks, Lurker and follower of all your work and knowledge. I’m another follower of Capn Crunch and racrx7’s pioneering ways… Got my 236 wired up last week, I thought. Got it working, and switching into all gears one night, the next day I came to clean up the wiring and put everything back togeth...
