the plug connection is at the bottom of the alt....I first extended the wire with a new plug with longer wire....the check gauges light on the dash came on..could not figure it out.....called mechman and thats when i found out I needed the H104 wire harness....install that wire harness and the dash light goes off

Interesting....Ive had the battery light on after installing random aftermarket alts in various cars. I wonder if running an additional 12v switch wire like that would of remedied it.

Oh heck yes. I've had that stupid light on for several years and hadn't been able to sort it - and was way past any warranty on my Mechman.
