I believe the red goes to a hot+, black goes to coil-, green is ground and blue is for light

If I remember correctly, the red is 12 volts power, black is ground, blue is light, green goes to the coil. Good luck!

red line depends on what motor you have and what mods, at 65 it could be any rpm depending on gearing and tire size

Joe, Them 4:10 gears are hard on the ol FE. That thing outta leap off the line, and get 9 mpgs.

I have my tach red line set at 4000 rpms. I did have it a touch past that wednesday when I ran my ol boy up to 90 in second. My 3.00 rears help make that happen.

2050 at 55 mph.

John

Took it for ride today.Bout 3 grand at highway speed.Speedo is a bit off but I/m guessin 65 or so.She really does jump off of the line and gets 6 gallons to the mile or so it seems.Mostly use it to go to the dump and grocery runs on the weekend.
