Bought one of the fast reacting sensors from wannaspeed with the plug and play harness. Decided I'd swap it out in a few minutes. Then I actually looked at what I was doing.



Oy!
The IAT is the thing with what appears to be masking tape on it at the top of the picture.

I guess the PnP harness was pointless and I'll be splicing wires... ugh.

BTW whats that orange plug?

So it looks like... it's for the PRC.

 

Since you have some "re-wiring" to do anyway, you might want to consider re-locating the IAT up-stream a little and away from heat-soak. I just cut the sensor 'probe' off of the bad sensor and used it as a plug on the UIM. New sensor was located in the throttle-body elbow.

 

Yeah I was thinking the same thing. Only issue is that I will be putting a vmount in here soon, so I'm not sure where I want to put the sensor. I might just wait till I get the vmount ready.
It's going to need a greddy elbow, so I can put the sensor just before the elbow in the IC piping.
That makes sense right?

 

That's where mine is at, after the IC but before my AI nozzle and t-body.

 

How long do you need to extend the harness to put a new sensor on the TB elbow?
Does the PnP harness extend it sufficiently for that?

 

13.81 inches....

Measure it dude.

 

Well the PnP harness gives me a few inches, but its pointless since the part that would plug in is probably non-existent on my car (based on that pic)

 

Extend it, and mount it on the intake elbow.

 

lol
