okhave read thru the FAQ, done a bit of reading on forums. and I'm still lost. electrical stuff isnt my strong point.

 

Anyway, i have Denso external regulated Alternator. it has a 3 pin (i think) plug that connects to the back. and next to that is a Pole with a nut on it. from what ive read its the "B" pole??.

To charge battery i presume you need a wire from the B pole to the + of the battery yes?. In the FAQ it also says the "main relay" has a wire that also goes on the B pole.. where and what does this "main relay" do?

from the B+ pole on the back of the alternator a thick wire should go to your battery yes.

 

That is just where the main relay gets its power source from (B+ = Always powered, Not accessories or ignition switched).. Couldn't really tell you what it does unless I could see the rest of the diagram..

think i may have solved me problem with this, there is a plug that goes from battery terminal + the from plug it splits into 2 wires and then joins into a 2 pin plug. then off that plug one wire goes one way (i think) and a thicker wire goes off to a plug that i have no idea whats it for. safe to say i connect a wire from that to the B pole on alternator?

 

Also, how are the reverse lights hooked up?. seems i have a 3 pin plug doing nothen near the brake resivoir (maybe for a brake level indicator?) and i allso have one wire thats a male bullet connector, and the other is a female "spade" connector. they are grouped together and site opposite the drivers side engine mount... safe to say they are the reverse light connectors?
