I have a 89 150 XR4 with the old style water cooled regulator and need some help with the wire connections. Does anyone have a wiring diagram for this area of the motor they could share. I have a number of different service manuals but none of them address this area.

Thanks

Yellows go to the stator. Red goes to battery via the starter solenoid, and to the trim solenoids. Grey bullet connector goes to tachometer wiring. Purple goes to switched 12V, I believe at the terminal strip over the switchboxes.

hope it helps

Thanks John,
I appriciate the help. I think going up through the termial block is what is throwing me off.

The heavy ones (yellow and red) wire through the block. The others are just plugs.

So..there is no real wire sequence meaning yellow #1 goes to yellow #1 on regulator etc.. John?

Thanks
