Re: 1968 GMC - Ol' Blue

Also got my fans and fuel pump wired up and running. I used the GM 3-relay setup for the fans so they both run half speed when the PCM calls for low-speed and they both run full speed when the PCM calls for high-speed. This is a fuse block/relay setup I got from Amazon for $30. I looked at the Bussmann setup and it's nice because it has internal bussing to make wiring a little easier, but I would have spent over $100 because there is a minimum quantity of seals and terminals so I would have ended up with hundreds of them that you don't use. This block worked pretty well - I soldered the 10 ga wires to the terminals since they weren't big enough to crimp. Other than that, the seals fit tight and I'm pretty happy with it. Don't mind the labeling on the wires, we just used leftover wiring from my AAW harness to match the colors used in the GM diagram.

And the intake is done. I used the Spectre 9900B (B for blue filter) kit along with a straight piece of 4" tubing and another coupler to get the clearance from the alternator coming out of the throttle body. I cut off the long mounting arm from the long section of tubing and fabbed up a custom aluminum bracket to firm up the tube to the alternator bracket. Just a heads up for anyone using this kit, it utilizes a clamp from the stock 99-06 intake. It could be done without it, but fortunately we had the part we needed from my dad's 06 leftover as he has a K&N system on it.

I went to prime the fuel system and I've got a couple leaks that I need to figure out. One is the single outlet from the fuel filter/regulator and the other is somewhere at the pump. So here I am regretting the Tanks Inc setup again.
