need 93-94 ecu and tps pinouts
i got my ecu back from being rebuilt. car runs better. exhaust doesnt smell funny at idle anymore, but it still bucks if you push the gas too hard. i get code 41, tps signal. ive already replaced the tps. same issue so it must be a faulty wire from the tps to the ecu. if you have the pinouts please post them or send them to me. its easy to rewire the tps if i have the pinouts knowing where the wires need to go.

90-92 ls400
tps pin 1=brown wire=gnd and goes to e10 pin 18
tps pin 2=green wire=idl1 and goes to e9 pin 1
tps pin 3=yellow wire=vta1 and goes to e10 pin 4
tps pin 4=blue with red stripe=vc and goes to e10 pin 11
e10 is a 22 pin connector
e9 is a 16 pin connector
tps pin 1=brown wire=gnd and goes to e10 pin 18
tps pin 2=green wire=idl1 and goes to e9 pin 1
tps pin 3=yellow wire=vta1 and goes to e10 pin 4
tps pin 4=blue with red stripe=vc and goes to e10 pin 11
e10 is a 22 pin connector
e9 is a 16 pin connector

ok, the 90-92 is different. found out yesterday. luckily i found the diagrams for the 93-94 but it was so late i didnt mess with the car anymore. ill try to fix it tonight when i get home. i was able to confirm that the tps does have a good vc and ground. as for the other 2 wires idk. i checked the tps i installed and it tested bad, but the origonal i pulled off tested good so put it back on. same issue. im hoping its just the vc to vta2 that is missing so i can just jump those 2 pins. this problem is really annoying.

ok, just to post this for others that might need it. this is for 93-94 ls400
pin 1 of the tps is gnd. brown wire. goes to connector c pin 22. wire is also brown
pin 2 of the tps id idl. green wire. goes to connector b pin 32. wire is also green
pin 3 of the tps is vta1. yellow wire. goes to connector c pin 7. wire is also yellow
pin 4 of the tps is vc. blue with red stripe. goes to connector c pin 1. also blue with red.
now if you DO NOT have traction control
connector b pin 31 is idl2. goes to connector c pin 22 gnd. brown wire.
connector c pin 1 is vc. goes to connector c pin 12 vta2. blue with red stripe.
connector b is a 34 pin connector from what i can tell from the diagram
connector c is a 22 pin connector from what i can tell from the diagram
i hope this helps. if the dealer ever says you have an open on a tps wire and need to buy a new harness this info will help you rerun the wire to save a grand or more.
