Splicing 3500 MAP sensor

[whitelightnin04MC]

Anyone know how the wires on the engine harness are supposed to splice to the 3500 MAP pigtail. My pigtail has gray, green, and black from left to right with the clip side of the connector facing up. Which color wires on the harness in my engine bay go to those wires on the MAP pigtail?

Thanks in advance.

this is sweet, you are asking all the questions i will be in the next couple weeks. Bump for some needed info. I wish i could help though.

Yeah? That's cool. I'm glad I can indirectly help someone out. I just got everything I need to install the plenum. The plenum came in last week along with the tb adapter and the FPR adapter. Yesterday, I went out and got a die grinder with a few bits for it. I went to pepboys today and got vacuum tube and a couple of fittings.

So far, I've degreased the manifold, ground down some of the casting seems, wire brushed the paint pen and grime off of the manifold, and opened up 3 of the ports. Tomorrow, I should be able to finish the porting and get the first coat of paint on it.

Time to get ready for the work week by ingesting a good bit of tequila before work tomorrow morning.

This is how I did mine... seems to work :P I didn't throw any codes for MAP (that I know of yet at least).

Yeah gray to gray, green to green, and whatever is left over :P

Ingesting the tequila didn't go so well. Wound up very sick this morning. That never happens.

Anyway, thanks everyone.

lol if you don't want to cut the stock connector off you can use the weatherpack stuff at EFI connection to make a connector that is plug and play.

Does anyone have the pin outs for the 3500 map sensor? I was helping someone tune their car yesterday and we where having a problem with the map sensor. It just showed 77 Kpa all the time and didn't move at all with the throttle, and it showed 77 for the barometric pressure too which isn't right at all. He's got a 99 grand am se 3400 with a 3500 top end swap, and is using the 3500 map and 28lb injectors. Ben made him a harness for the injectors and map. The 3500 map should have the right output signal and should work with the pcm right? So I'm thinking either the wires are in the wrong spot for his car's harness, or the map itself is bad. Gonna try to get the 3500 map to work so we don't have to switch back to the 3400 map and adapt it to the mani. Here are the wire positions for the stock harness connector.
