Hooking up External Tach!!!!!!!

Does anyone have an external tach that they added to their stock B2200 interior? How exactly do you wire it up properly? There are 4 wires: Black, White, Red, and Green. I'm sure one of them is power, one is ground, anyone have an idea as to which connects to where?

Thanks...........

Black: Ground
White: Illumination
Red: Power
Green: Ignition Coil

Its been a couple of years since I put my Sunpro in, but those should be the hookups.

i'm putting one in.. prolly next week or the week after.. i bought a skull and frenched it in one of its eye sockets.. looks pimp.

PS- pics will be up when its in

There should be a wire on your coil that was put there just for a tach i found it on my 88 b2200

thetornado is right. Just make sure you hook the green wire up to the negative side of the coil and not the positive.

HAHAHAHA......rember that one. HAHAHAHA

I still think of my old Autometer sometimes.

Just make sure when u hook up the Illumination you hook it up to the dimmer switch and when u hook up the power run it off a key on hot!
