I cut the purple starter wire on the passenger side and wired in a 25 amp toggle switch. Is the switch going to burn out or is that a high enough amp rating to use.

I see that some people use relays but I'm not real clear on how to hook that up and would rather not.

 

Drive up to my shop in Portage WI, and I will help you wire up a relay seeing as that should really be a 30 amp. But if you have a 4th gen, it already has a starter relay for the VATS (PASS KEY II).

 

Thanks for the invite but I just don't have the time (or gas money) to go all the way up there. Is it a service shop? Maybe sometime in the future because I think my fuel pump is going.

Anyways, I bought a 30 amp and 50 amp switch and am deciding on which one to use.

 

30amp is fine. My shop is a custom shop, "KINGSLAND CUSTOMS" I have been doing LT1 swaps since 1995, put them is 70's muscle cars, like F-bodies and vets, and S-10 trucks, and about everything else including Porsche 944's, Datsun 240Z's and RX7's, also do superchargers and turbo chargers, custom paint, work on stock cars, we sponser 4 stockcars right now...

 

I wouldn't run a starter kill switch without a relay, not when for under $2 you can do it the right way and not worry about your car burning down.

 

I would use a relay, too...or just make use of the theft deterrent relay that is already there...

 

Could you explain why a relay is needed? I don't understand why they are needed.

I ended up using a 50 amp switch. To me it doesn't seem like there is any need to worry about something going wrong.

 

I noticed most push button engine starts have relays.

 

That's why you don't see what could go wrong. someone prolly can explain it better than me, but with a relay, all the power is going thru the relay, not the switch. You might be safe with what you have, but I'd much rather have a relay. They are needed because without them it can cause a fire when the switch over heats. I've seen it.

 

Anyone have a wiring diagrahm of this?

and where are you splicing the wire? under the dash or outside the car?
