Buddy's schematic is excellant.I put my relays on near the underhood fuse panel on the 95 Tahoe.
I used the underhood fue box for a power supply and tapped into the grey wire to the lift pump and off the glow plug controler to activate the relays

Thanks for the pic's Jrs their helpfull I'll see if I can locate these place's you tied in. I just got my extension hose from PMD, I thought this hose was suppose to be about 6'' long ,this sucker I got is 24''. I don't know if he made a mistake or I'm mistaken about the length of the hose.

That is Leroy's latest and greatest extension, allows you to mount it to the intake or anywhere even easier to get at. I have that one too.
You can get power directly from the wire to the OPS connector, if you tap into it, or anywhere like jr did. The grey wire you can also find right on the OPS connector. You can cut it several inches from the connector and use the two ends, but you probably need to splice more wire into each end. You're going to be messing with the OPS connector just to relocate it.
