Hi guys,

A bit of advice if I may. I'm installing an AFR gauge (I know, not the best of gauges but it's the second part of a dual gauge so I want to see it working).

My question is... I'm about to wire it into the lambda wiring in the engine bay but there are 4 wires.. 1 blue, 1 White and 2 black. Which one should I be wiring it in to?

It's an 04 WRX if that's any help?

Thanks, James.

If you look inside the connector, one the terminals should be a gold/bronze colour, that is the signal. You can also, as i have, take the signal from the ECU plug, much easier.

Yep, that's right, any ideas?

I did try that... White and blue wires have gold connectors and the two black ones have silver, lol!

Didn't want to play around with the ecu wiring in all honesty, I'm not that great with wiring at the best of times!

The 2 black are heater wires and the white and blue are signal wires, one in, one out be which is which??
Do a search on here, it's bound to be there some where.

When i fitted mine, i was advised to connect at the ECU end of the loom for a better reading iirc.
