I believe that's the part number. I didnt order the harness though. Im going to wait to see if the plugs match before ordering anything else.

I was checking with a volt meter wow the dip is huge when the engine resumes auto stop resume The voltage goes from 14.6 to 13.4

for a fraction of a second this dip could cause "computers" to shut down unexpectedly. from the power surge when it goes back to 14.6... and cause a stall out



I can see why this happens (i.e stalling or lagging )


120amps 1.6kw for the transmission pump is a huge load ( lets just say it's close to the rating of the two fueses for example)

120amps for a little fluid pump sounds crazy high with those little wires. has anyone put an amp clamp on one? that's wild.

wires that size on a gm, I'm used to seeing maybe 40amp load run thru.

my bad it has a 60amp fuse i 'm still thinking about getting a capacitor and a solar panel to keep it topped off... i see an issue with the battery posts going to get some
Battery Post Shims i noticed the battery quick release connectors damaged the Battery posts(crushed the lead)

have you considered replacing the hybrid battery? I feel like that would solve or at least eliminate that as your underlying issue.

Yes I am considering one of these it's 3,000$ while a new battery from GM is $6,000 including core..
it has 260amps output power compared to the normal pack of 100amps

i'll have to save up some $$$$ first

Hello, Here is what i got from the dealer, The wiring diagram is listed, I’m looking for the order of the plug, the 4 wires plugged in without a harness but I’m stuck with a 5 wires harness which is discontinued.
