Thanks for all the help fellas, I'm going to go ahead and have the shop put the gauges in for me. Even if I leave the manifold in place, I've still got the wiring to deal with. I'm sure given enough time I could hook everything up right, solder all the connections, and everything would be fine. However, I remember back to my first truck, an 89 chevy, that had wiring (done by me) that look like a dang bird's nest under the dash. I had wires going everywhere between the tach, driving lights, and amplifier, nothing ever worked right. The shop I'm going to was recommeded by a friend, and fellow TDR member, and in talk with the owner, I feel I'll be better off having someone else do the work.
