Thumbs up Re: More tach wiring confusion...please enlighten dumbdum

Ok, I took a picture of the box schematic and down loaded it and here it is. You should be able to follow this and it should work. LMK what you think. The tach wire you have coming off the tach should go to a YELLOW wire out of the Summit box. The 12 volts should be like factory unless the box states other wise.
Question for you? Why do you need the box? If your using a HEI then why the box?
Second ???

Knowing what I do now I would have just pulled an 80'sish GM hei and been done with it.
Are you not using a HEI now?

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
