Hello all,

I was looking at LT1swap.com and noticed he is powering his ignition + by using a 30 amp relay. I'm going to be running an underhood fusebox that has two busses: one buss is batt+ and the other buss will be ignition +. I'm going to power the ign + side of the buss by running a jumper wire from one buss to the other powered by a relay which will be activated by the old HEI ign+ start/run wire. I'm going to have a lot more wires going to my fusebox, but I think that's only because I haven't combined as many together into one larger wire. Will a 30 amp relay still be suitable to power all of my ignition+ connections ? Would 10 gauge wire still be enough to power the entire Ignition positive side of the fusebox?

Thanks,
Brandon

There's no reason to do anything differently than exactly how lt1swap is showing you.

I believe we've had this discussion.

Amp rating will depend on how much you are going to put on it, but to run just the ignition side of the engine harness then yes it will be fine, I have been running them for years.
Wire gauge to the relay will depend on how far the battery is from it.

Gotcha. Thanks,
