Sirs, I purchased your Pow'r Converter Model 300 about 20 - 30 years ago. I had installed it in a Ford F-150 pick-up. I used it to power my hand drills, jig saws, and other equipment in the harvest field. I also used it to power my chain saw when I cut up wood for the stove in my shop. I enjoyed the convenience of the converter. I sold the pick-up but I kept the converter. I do have the instruction and installation manual but need more information on installing it in a different vehicle. I do not have the light the manual speaks of. I remember it in the old pickup but didn't take it out. Could you send me information or preferably a schematic I can use to rehook up this unit. I may install the unit in a 2003 Chevrolet Cavalier or another pickup.
