I just basically need to wire these two up and my loom is finished!!!
Lambda sensor - 3 wire's, colour's of wires are: brown (earth?) white/black (signal?), brown/blue (power?). When I tested the Lambda sensor on my Astra, the brown/blue had about 4.5v going to it. Going by the C20XE wiring diagram though, the white/black connects to the fuel pump relay. According to the Emerald wiring diagram there is pins for the Lambda sensor input, Lambda sensor earth and that's it!?! So would that mean that the sensor get's it's power from the Fuel pump relay?!??! If so, then the wiring diagram in the haynes manual does not make sense!! lmao
Coil pack - I bought a coil pack from SBD which has four pins on it. The Emerald wiring diagram has the following: Ignition driver 1 & 2 and a 12v feed. What's the fourth wire???
