mikec Posted January 13, 2013 Share Posted January 13, 2013 Hi guys, it's cold today my hands nearly numb :0 Anyway does it matter which wire goes to which pin on the cts, mat, and pwm valve plugs? Can't seem to find anything to say if it does or doesn't matter? Cheers mike Quote Link to comment Share on other sites More sharing options...
mikec Posted January 13, 2013 Author Share Posted January 13, 2013 Oh while I'm asking questions, I'm also unsure which way the wires are wired on the lambda, think I have two white a grey and a black on the lambda, which one goes to which on the ms wiring? Cheers again. Quote Link to comment Share on other sites More sharing options...
muttleyd Posted January 13, 2013 Share Posted January 13, 2013 Think on the sensors apart from the crank sensor it does not matter which pin. The two white wires I think are for the heater one to positive one to earth. The other two to your relay board or d37 Quote Link to comment Share on other sites More sharing options...
Quagmire Posted January 13, 2013 Share Posted January 13, 2013 White wire wil be sensor heater so connect one to +12v and the other to a good earth. The others are counter intuitive and so grey is sensor earth and black is signal. Connect grey to the low current ms ground wiring where the other sensors (clt and iat) feed back to and then connect black to the lambda signal pin on the ms.

muttleyd Posted July 13, 2013 Share Posted July 13, 2013 Just resurrecting this to confirm as I thought I understood. When wiring with a relay board, the blue wire from the board goes to the black wire on the fuel parts sensor. The grey wire from the sensor then needs to go to an ecu earth. Seem to remember Sam used one of the relay sockets for the pwm relay. Have I got it correct, as am just about to wire up a super seal plug?

Mr Noisy Posted August 9, 2013 Share Posted August 9, 2013 Yes I picked up heater earth and sensor earth at the redundant idle valve socket. This was mainly because there isn't actually any earth sockets otherwise available on the relay board And also my innovate lc1 destructions said to keep all the earths together.
