Whats up guys? Ive got a 1992 camaro rs that was originally a 305 TBI and i have since pulled that motor out and am swapping in a carbureted 355. My issue is with the wiring that im going to have to do. I am wanting to keep my stock gauge cluster and all my stock gauges but my question is can i just install sending units in the new engine hook them up to the factory harness and have all my gauges still work? I plan on leaving the factory harness intact minus fuel injection connectors and such that i dont need. Im also wondering the best way to retain the factory in tank fuel pump? I plan on running a holley fuel pressure regulator with it to bring the pressure down to about 6 psi or so for the carb but im just wondering if anyone has done this before and knows the best way to make the pump run off keyed voltage? I plan on running the cooling fan the same way whenever the key is on the fan is running because i usually only drive it in the hot summer anyway so if you could give me some advice on wiring that up as well it would be greatly appreciated!

 

I'm doing the exact same thing in my ride. I don't know about the gauges, but the stock fuel pump should work fine still without any modification in wiring. The way I make my fan come on is by turning on max a/c ( I have no hvac system anymore).
