I have an 8 in my 9 on my car - the old engine was originally from a 2wd car, and so I have a mix of 2wd and 4x4 parts on mine. Very confusing!

I doubt you can mix a 8a switch with a 9 thingy, only 8a with 9a and 8 with 9. That's probably as clear as mud!

Bascially you will prob need a 2wd pressure switch and the part no 9 to make it all work on your car. Remove the 8a and 9a from your car.

I also have an SPA oil pressure sensor tapped into my 9 as well making it even more of a headache!

Bloody confusing when it comes to ordering bits for it
