Inhave a 09 ls2 and i am using a GM 19166568 control pack. My cam and map sensor plugs are different than the sensors i have. The plugs look the same to me. I have looked and looked but i cant find any sensors that match.
What sensors do i need???
Any help would be much appreciated!
I found the right plug for the cam sensor and re pinned it but i haven't found the plug for the map even though EVERY map sensor i have looked up looks just like mine?!?!?!
I remember running into something similar with the MAP sensor. Are you sure that there wasn't a little jumper harness that was included in the GMPP ECU and harness kit. I recall there being a small jumper harness with my kit. I didn't use it, and I just robbed the correct plug and installed it on the harness.
Be careful the jumper harness (LS2 to LS3 map sensor harness) can be pinned incorrectly and your vehicle will not start. I have one pinned correctly that'll I'll post up. But that is a LS3 map sensor and a 58x cam sensor.
Adapter harness correct pinout (letters and number are on the connectors) My harness has factory type colors so your colors may be different but just put A to 2 etc etc on your adapter harness if it's not correct.
Ls2 plug= A pin: orange / B pin: green / C pin: grey
My LS2 24x harness connector plugs directly into my spare 58x cam sensor. (And of course the 24x cam sensor) I don't know the correct pinout for that though or if it's the same. So your harness should plug into the cam sensor but not the map sensor.

I swear that my GMPP kit (I got the LS7 kit) included that jumper harness. I also remember having to be careful with the pinouts, because they were different.
Yeah I remember that a lot of the adapter/jumper harnesses made for the ls2 to LS3 map were pinned wrong. It caused me a couple of days worth or headache back in 2010.

Thanks guys for the help.
My GM kit did come with a jumper harness but it was wrong. It has a simillar connector as the cam sen.
After a heap of searching i found the correct plug for my map. I will just pin it the same as the other connector. Luckily the GM kit instructions did come with color code and position on connector.
Thanks again.
Just a little laugh on this, today i was workng on my stock porsche harness lengthening some stock wires and one of the plugs on it matches my map perfectly!

This does not surprise me since I do believe that the LS3 MAP sensor is made by Bosch. I think the connector is made by TE Connectivity. I had a good relationship with my local Chevrolet part counter guy. He let me rummage through their stack of terminal boxes and I was able to find to right terminals so I can crimp my own connector. If you care enough, I can probably find the part number for the terminal, just let me know.
