Put the harness, and ECM in a couple of weeks ago under the drivers . As I can't have a passenger seat.Then coiled the engine part of the harness over the right valve cover. Ran a wire up from the starter solenoid to attach to the Howell harness. Then another wire up from the knock sensor. Did the exhaust sensor bung a few years ago. I'm leaving the carb electric pump, and tubing in for now. And that carb pump will draw out of one tank only. It's the just in case thing. Putting the two EFI fuel pumps/filters on the outside of the frame with a thick aluminum cover over that area. Remove the valve that controls what tank the fuel is drawn from. That dash switch will now control what tank pump is used by way of a relay. Using a 3/8 insolated steel line from the pumps to the TB. Fuel return line will go into the tank fill vent line. Then next install the ECM controlled HEI distributor.

Bob,

I am looking forward to hearing about your installation.

I've been talking to JimK about installing this system over the winter once I get my coach back from the shop.

Keep us posted!

Bob
