Hotwire Wiring questions

c. Yellow – Ignition start. (ignition key cranking position only) You must use the included starter solenoid wiring for the engine to start properly. (Mopar muscle cars: You will need to use a momentary push-button starter switch with this wire on one post and 12v on the other post, the dual ignition circuit of a late 60’s to early 70’s Mopars will not work with the Hemi system) - Is there a work around? I really don't want to use a push to start button and a key. I'd rather just use the key.

You can try to wire it with the key and see if it works. Some ignition switches dont break contact between start and run. Be aware MOST do, thats why he says to use the push button. That momentary break in the power circuit will trip the ASD relay and you'll have a no start issue. I got lucky with my switch and it works. Some guys have just wired up the start and run circuits together and had success that way with the switch. I am running off memory on that last part- you might want to double check on that.
