Couple of new supercharger install issues

[whylee]

Im installing the Chevy Colorado Magnuson supercharger kit onto my 08 H3 Alpha. Received the supercharger today and ran into a couple issues. 1: the oil pressure sending unit for the H3 5.3 does not fit the new valley pan in the kit, the threads are different, it also appears that the electrical plug is different than the one used for the Colorado. I can use the Colorado sending unit, just have to figure out the electrical plug issue. 2: the map sensors are different, the Colorado unit uses a O ring while the H3 does not, again the electrical plugs are different.
I can use a Colorado MAP and splice the harness extension that came in the kit into the H3 harness.
I can not go any further with the install until I find a way to get the oil sending unit wired otherwise I can not reach the harness if I have to. Any ideas?

Do they both have the same amount of wires going to each other? If so just splice the connector from the truck to the SC.

Schwarttzy.com has alot of H3 wiring diagrams. It may have one of the connectors you're looking to splice.

I will check it out, thanks for the info. Another difference I noticed, but has no effect that I can see is the valley pan gasket. The gasket for the H3 goes around the entire valley pan, the one for the Colorado does not go around the oil pressure sending unit port. Unless they gave me the wrong gasket, The valley pan that came in the kit looks the same on the bottom side (gasket side).

They have the same amount of wires, my concern is that they respond the same if I splice them in.

Wire is wire as long as you have them hooked up correctly you'll be fine.

if all of that fails... the guy who does the wiring for 150tunes.com is a GM tech (he did the wiring harness for my Fiat spider - caddy cts motor). He's one of the nicest people I know, and one of the few mechanics that I recommend.

I'll try and get you those install instructions, I have it on a USB drive, and only have my iPad in the house right now.... Soon
