Goes to the small terminal of the starter(solenoid)
Since I have the foot starter, where would I connect this?
Connect it to the small terminal on the solenoid that the foot switch wire connects to.
Also, what is the best place to get my 12v when the key is on?
I design all my stand alone EFI harnesses the same, The battery 12V should come straight from the battery post on the starter solenoid. That means the GM main red wire that becomes org once it goes thru a fuse. See my
step by step FAQ that addresses each connection.
For the 12v switched this is the pink with black and is 12V coming out of the power relay. For this you should have the battery 12V going to the relay on pin 30 for a bosch relay, and then to energize the relay(s) you should use the 12v wire that used to go to the +pos side of the ignition coil. If you had a ballast resistor then use the wire prior to the ballast resistor so you get the full 12v.
This should be shown in the wiring FAQ and the step by step FAQ's already linked.
If you have not read thru those FAQ's you should take a few minutes and review them.
The main point is that you should not use any of the original wiring to carry a load of the system. The 12V from the key switch that went to the coil must be hot in the on and the start position. And it should only be used to energize the relay.
You should have your ignition 12v now coming from one of the 2 relays that power your system.
I normally use 1 relay to power the fuel pump and the other relay to power the system and ignition. i also use a min of 14ga wire to feed the coil from the relay.
