Injection Pump wiring

[JStokes]

I am still working on the Suburban conversion and am wondering about wiring the IP. It looks like there are 2 places where I can wire it. Is the top wire the fuel shut off solenoid and should it power with the key coming on? What is the bottom one and when should it recieve power?

JS,



I only have one wire and it's on the top. I have been told that it doesn't matter which one gets the wire.

mine has two male spade terminals on the shutoff solenoid, i dont think it matters which one you hook to. there is also a male spade terminal on the ksb, but i haven't paid attention enough to see where it's wired from. i'll take a look tonight and get back in the am.

One of the spades gets power when the key is turned on. The other spade takes power to the temp sensor in the intake that is used to turn on the KSB. The return from that sensor goes to the spade on the KSB solenoid.
