    GTX BP26 ecu diagram? TPS conversion (3 to 4 wire)

    I've searched and read alot of helpful information about my 3 wire tps to 4 wire tps conversion. I have the TB from an auto BP with the 4 wire tps, I'm running the 4th wire to the slot on the ECU instead of the wire on the VAF. I need to "rearrange" the other 3 wires for the tps in the correct spots on the GTX ECU. I can't for the life of me find the diagram for it, I have the diagram for a BP but it is a 3 wire tps ecu.

    Believe me, I have searched. I have also bookmarked every page on tps conversions on this site. Very helpful I might add. If anybody has any more helpful information on the TPS conversion lets hear it! Thanks guys.

        you don't want to remove that wire from the AFM, just splice off of it.

              neuman you should check out jacobs MS how to also, if you havent seen it yet. should be helpful for anyone wiring in any standalone though.

                    according to link this is what you do for the 3-4 wire tps convertion.

                    ((Just put the 4 wire tps on my GTX, it wasnt hard but it took a lot of looking through diagrams and piecing together information. I took some pictures and figured I'd post up some info on it for everyone else.

                    All you really need to do is put the throttlebody on, cut the 3 wire plug off and connect color to color, run an extra wire to the ecu and connect it inline with pin 6 the wire is LG/R and move the LG/W wire from pin 19 to pin 7 on the ecu plug, pin 7 is between a red wire and LG/R wire.))

                    ok so when you repin, pin 19 to pin 7 do you just leave the origanal wire coming from pin 19 taped up, and the wire that use to go to pin 7 taped up??

                    I.E. pin 19 has a wire coming out of the plug, you cut it and move it to pin 7 well the part of the wire that stil hanging in the plug do you just tape off or does it need to be coneted nad the same for pin 7 wire that you have just haning there????
                    it kind of hard for me to explain, hope you guys understand what im trying to ask.

                    also as for the 4th wire on the tps 0-5 volt signal can i just splice it to the vam 0-5 volt wire???
                    thanks

                      so i would have to change wires at the ecu to put the 4wire throttle body on?

                            a somewhat related question
                            is 15 (1M) an important ground?
                            Is everyone just running this with out grounding it like they do with everythinng else?

                              "so you have a manual harness and you put a auto tps right?? you want to use the gtx ecu?? wire W/R its the same for gt and gtx, wire LG/W you moved from 2L(pin 19) to 2M(pin 7), B/BR its ground stay the same for both, the other that you need to add go from the tps to 2K( pin6) color LG/R"

                              Just do this, I repinned the ecu so the only splicing was needed at the tps harness. For the 2k LG/R wire I just tapped it right at the VAF in the engine bay. On the GTX that wire feeds 5volts to the VAF, and TPS.

                              To try and clarify, just splice the wires so they match at the tps then repin as above. The extra wire gets tapped into LG/R.

                              This might help too. http://www.wihandyman.com/forum/show...d=1#post366349
