Need some help guys and girls.

I'm helping a mate out back in Australia, but to do it right I need a copy of the turn signal circuit out of the factory manual for a Trans Am, would prefer the 87 so I know its the same as his car.

I've searched both this board and the ones linked and I couldn't find anything. He linked me to "a" circuit he found on the net but it is both inaccurate and missing vital information.

Please guys I REALLY need this to help him out so he can get his pride and joy on the road.
