from TIS, Z12xe connector X53 is body to ecu plug, red/white wires are in pin locations,
4 = tps (b22) connector X14 pin 42. pin 1 at pedal sensor. this is from pin 55 in the Z18xe connector X57.
there should be 3 more red/white wires from X53 on a Z12xe from pin locations 17/33/49, they all join together and go to relay K26 ecu, which is the purple relay at the front of the main fuse/relay box on the left viewed from the front of the car (nearest the engine)
for the Z18xe they will be black and red from pins 31/47.
hope this helps?
