I put a new pigtail on a impact sensor but the wires are different color how do I know which one goes where? There are only two wires

funny i just did this.
they sell the pigtails lots of places , mine is off ebay , close to my state
here is how < I used heat shrink tubing
first I took the old connector in hand
and I see the pin numbers clear as day..
'but of destroyed,(a key word) I get the colors off the SM my car I have my real service manual and for sure covers colors.
per pin, all that.
seen here

the aftermarket pig tails are all black.(as they MUST)
that is because this connector is used on vast things cars vast. and devices and makes of all cars. too. endless .... end worry here.

so there no color there.!!! on pigs.
on paper write all that down. pin1 color and all.
then on harness, i cut it back to fresh wire colors.
and solder them on just after heat shrink is slid on,far.away 6"
then slide the HS forward covering joint solder and heat it with my heat gun. (on my car pulled whole harness out.)
repeat times all pins down.
the then put my handy thermalShield(tm)T6 warp over all that rated for 1400deg F. and will never fail again.
used on jet engines, cost me 5 whole bucks.



the yellow is F4 silicon self fusing tape., silver is thermalshield. T6
factory junk warp fails in only 60,000 miles, at 200f close in points.
intake top off. and factor wear point cured too, big yellow below.

go ask a dealer we do not know what you have

the connector is the same on both the old harness and the new pigtail. As long as you orientate the connectors the same way you just match up the wires. let me try to explain it this way. If you hold the old connector so the part that holds the connector to the sensor is facing up. Hold the new connector exactly the same way. cut the left wire on both and connect the new connector wire to the old wiring harness. Then cut the center wire and connect them. then cut the right wire and connect. No wiring diagram needed.

One thing I will add is to stagger the new connections. Meaning do nut cut them at the place. Cut one wire then cut the next about an inch or so further and then cut the next about an inch or so further than that. This will prevent the new connections from potentially shorting to each other and will keep the harness from becoming really bulky with all the but connectors in the same location.

You may need to buy a shop manual from Ebay.
All I have is for a 1999 model, nothing for 2000 - 2006.
The 1999 version shows a white red wire going from terminal 3 on the sensor to the ECCS relay, a red or white wire from terminal 2 going to terminal 48 on the ECM, and an orange or green wire going from terminal 1 to terminal 47 on the ECM.

Okay here we go, there are three wires from the map sensor, if you look at the sensor there are letters stamped on the plug area, theres an A,B,and C the wires start from the sensor as orange/blk to terminal A then lite green wire to terminal B and last is gray wire to terminal C . im not sure what wires your freind cut but there only one at computer for map sensor and thats the signal wire, all slots at computer are numbered the signal wire is light green and connects to slot #25. heres a diagram for all wires to computer you will need to locate the wire in order to connect them back, this is not hard find the open slots and check diagram for wire color, hope this helps, good luck.

As long as you are talking about the new body style ( 3V 5.4 L )

The module is the MAFS and the IAT sensors

The IAT section is :
PCM to IAT is Gray wire
The return to the electronic engine controls from the IAt is Gray w/ REd stripe wire

The MAFS
PCM to MAFS ( MAF ) is Light Blue w/ Red stripe wire
The MAF return on the PCM is Tan w/ Light Blue stripe wire
The ground ( same as the Charge motion control valve ) is Black w/ White stripe wire.

Your best bet is to go to mitchelldiy online and get the wiring diagrams. Not knowing what year your car is and what harness or computer or component your talking about and since the wiring harness may not be the correct one for your application I would be hesitant to give advice that could ruin a computer if hooked up wrong.

Usually Wires are color coded, and if you have multiples of the same color you will most likely need the old pigtail to identify which wire goes where in the pigtail. If you don't have the wiring diagram handy that's the best way to do things. Haynes and Chilton manuals have those with wire color information if you don't have the original pigtail to use as a reference. Without more information on what area you're working on, I can't be of any more help than that as some sensors have multiple voltages that go to and leave them from the computer it's connected to.

GOOD LUCK
