launch control not working when switch is flipped. i wired it up on a separate toggle switch and one from the mega squirt and other one from chassis ground and flipped the switch and revved up and nothing happened...help?

 

Try grounding just the wire from the MS, maybe you have a bad switch and make sure it's a good ground too. Make sure your settings for your tps aren't to high and preventing it from activating.

 

yeh it was a bad ground...thanx

 

Glad to be of service.
