Don't you want to tie in in front of the neutral start switch.
If you tie in at the engine you could accidentally start the engine with it in gear.

if you're referring to the fp relay mine doesn't look like that, there is a red wire that has 12 v on it, a two wire connection that plugs into the efi harness and an orange wire that go's to the fuel pump, I'll take a pic and post it.
