This is not ment to be a how to, but if you have any questions please ask.

When installing the FRIATS I read the instructions and was dissappointed; I "had" to cut my factory plug off of the harness. Ummm...NO.

I was also dissappointed with the new plug that is attached to the pigtail of the sensor. That metal clip was a pain to take off while the sensor was on my work bench. I definately did not want to be clipping and un-clipping that connector while under the UIM. Plus knowing myself I would loose it immeadtely. (I was right).

So I decided I wanted to use the factory plug and solder the pigtails to it and therefore no need to cut the factory harness. I came up with the idea to Melt the factory Intake Air temp sensor exposing the leads inside the sensor and soldering the pigtails to that.

To melt the sensor I first used a small blow torch but quickly realized it lacked the precision I needed inorder to melt the plastic close enough to the connector without melting it. Insead I switched to using the plain old soldering iron. That melted the plastic easily and had great accuracy and precission.

Unfortunately I did not take step by step pics but here are a few showing what I did. Should be able to get the general idea.

This pic shows the factory sensor after I melted the sensor element off of it; exposing the two wires underneath. The most difficult part for me was making shure I did not break the wires off of the plug. The pic makes it look very dirty and crude, but that was the best I could do. I do not see how it can be done much cleaner.


What I did after was strip the pigtails and use three pieces of heat shrink. Two to wrap the indivdual wires keeping them seperated, and a larger diameter over both wires to add stiffness to the connection to remove some flexibilty at the solder joint (to keep the little wires from breaking). Then solderd the connections and heat shrunk the heat shrink and ended up with this.



And this.



Remember that metal clip I said I would lose...well guess what..I lost it. So I had to use a piece of stainless tie wire. Good thing I never have to take that off until I relocate the sensor.

Before I trimmed off the excess.


And BAM!! No cutting of the harness needed



Hope this helpes someone.

cool idea, but seems like more work than its worth. I lost the metal clip before, but found it without too much trouble, but the twisted wire idea is a good one.

 

you know you can buy an adapter with the sensor right?

 

Yep wannaspeed sells a plug and play harness, I got one and it worked great.

 

It's an AMP/Tyco Econoseal 2 connector, same connector that is found on the precontrol and wastegate solenoids. besides the wannaspeed adapter, the pigtail is available here:

The MAP sensor uses the same connector except it is 3 pin.

 

Good to know

 

Didnt know that. But I did not have to buy it.

hah that's a lot of work to save $8 but good job at doing it yourself.

 

It was really only about 30 min to do the splicing from start to finish. That is including the time it took for the soldering iron to heat up. I guess the way I described the process it sounds like a lot of work but it isnt. I installed it on a sunday afternoon and had nothing better to do anyway. I am happy with the way it turned out.

Sometimes I just need the self gratification that I made something work. I just get tired of buying parts for the car that I can do myself even if it is only $8 dollars. Plus more money for parts I "need". Maybe someone can relate.

You go boy!

LOL ^....

I really don't see the big deal on cutting the harness.... I enjoyed hacking mine to bits while doing the single conversion. The OEM connectors get fried & brittle after a long time anyway.

Either way, good write-up. Here is your pat on the back

 

I'm quite looking forward to this part, just got my harness removed yesterday.

 

I try to avoid cutting harnesses. Then you have to deal with potentially failed splices, solder joints, crimps, whatever.

 

While u were at it though u should have relocated the sensor from under the manifold, then u would have.
had to extend the wiring harness

 

RENESISFDs car is extremely clean, I can understand why he wouldn't want to cut or hack the stock harness. Good work bro!!

 

Lol Dan, I did not understand the humor in that until I read the lyrics.


I will be relocating it as it says in the origional post. But why will i have to cut the harness then. I will just modify the length of the pigtail.

The reason is exactly what MOBEONER says. My car is clean and if I do not have to cut up my factory harness by taking the extra time (30 Min.) not to do so I will.

Thanks for the pat on the back.

MOBEONER thanks for the compliment
