[custardcreams58]

hi there i am converting my thriumph tr6 to use a standalone ecu and im using a bmw 318 throttle body with tps etc.

basically i am lost on which wire does what on the wiring loom i have a plug which has-

1: grey /white stripe
2: solid brown
3:brown / black stripe

now i may have the wrong plug for the sensor but it fits! so if possible can anyone tell me which one is the +5v , signal wire and the ground?
