Need help with wideband wiring Ms2 pnp
 

I have a '99 with a Ms2pnp supposedly built by Braineack installed in a turbo car. Which pins or connector location to I connect the wideband signal wire to?
Any advice appreciated, I'm trying to get this running for a guy that recently purchased it second hand.

Pin 23.

Is pin 23 on one of the 3 factory ecu connectors?

I opened the unit and saw 3c goes to O2 sensor

Can you take a picture of the unit? Not sure if this is an MS2 based on the DIYPNP or based on the MS2 V3.0 board. My suggestion was for an MS2 V3.0.

Can I email it to you?
Only have it on my phone.

It has 4 different size connector openings and there are 3 oe connectors and 1 open slot

Sure, my email is info A T mslabs DO T gr

Thank you I got it. Top row second wire from right on small connector.
Got AFR, now just need to start tuning. Thanks again.
