hi guys

trying to put a mazda 929 alt in my suzuki sierra and just trying to work out the pin outs on the new alt. there are 3 connectors the main + line connected by an eyelet, and a 2 pin plug on the back, with a white wire with a black trace and a back wire with a white trace. i know one of these is the lamp indicator and the other a magnetic field thingy (technical term there!). anybody know which wire is what?

its a mitsubishi A2T41477 alt that was pulled from a 929 at a scrap yard

any help appreciated
thanks
chris
