M@tt 77 Posted November 12, 2008 (edited) right almost sorted my turbo wiring, the final bit is the VSS the XM that the engine came out of had an auto gearbox and it had a 2 pin VSS attached to the gearbox however the VSS module had also been removed before i got it so i just have some chopped wires which i believe went to it. However as i understand it this was simply a signal amplifier and using a 3 pin VSS it doesn't matter that i dont have this. I've just spent the past couple of hours trawling autodata and old posts and think i know what i'm doing but would appreciate if any one with any experince could double check my findings. basically the 3 pin plug has a +ve, earth and a signal wire. i believe the middle wire is the signal wire and this goes to pin 9 of the ECU (according to Autodata CD) and as far as i can tell pin 1 is +ve and pin 3 is earth so is it simply a case of connecting these up in that order?? on a few diagrams it looks as though the +ve feed might also come from the ecu as well? almost in a loop as it were (from ecu through sensor back from sensor to ECU) Edited November 12, 2008 by M@tt Share this post Link to post Share on other sites
Ant 2 Posted November 13, 2008 This is mine from a 1998 605 Turbo lump, that had a 2 pin connection. These are the connections on the VSS box connection Pin 4 ---> 131J goes to pin 11 on ECU Pin 5 ---> 131? goes to speedo Pin 6 ---> 52V goes to switched live Pin 7 ---> 130C - Sensor on Gbox Pin 8 ---> 129V - Sensor on Gbox Pin 9 ---> M52V goes to earth Useful to note though that ECUs must be different depending on year etc. My 131J goes to pin 11 not 9 as in the autodata diagram.

M@tt 77 Posted November 16, 2008 just thought i'd post up that i think in fact the 3pin VSS wiring is slightly different to what i posted up above looking at the 306 wiring diagrams i have which uses a 3 wire VSS the VSS wiring looks like this and so the pin outs are as follows Pin 1 = Swithed Live Pin 2 = Earth Pin 3 = Signal to ECU so thats how i wired up, should find out whether its worked properly once i fire it up Share this post Link to post Share on other sites
jackherer 543 Posted November 16, 2008 Thats how I wired up an aftermarket speedo based on Grahams info. http://forum.205gtidrivers.com/index.php?s...c=92597&hl= Share this post Link to post Share on other sites
