Re: Howell install questions
Thanks so much for that information Leve (and the email of the instructions), I was really hoping you would be online today, as I know you have the Howell system. Actually it was through one of your posts that I learned about the Megasquirt project. I'm ready to install my system, as it is fully functioning on the bench.
Went out to the garage and removed that grommet thru the firewall and am pleased to have an opening sized large enough for the DB37 connector on the megasquirt harness. I'm locating the Megasquirt power and relay module on the passenger fender well above the starter relay. New ECU, near the old one. The Megasquirt harness fit perfectly in the old grommet and it looks like factory, I even re-used the old cable cover as I am thrifty (ok, cheap).
I hope to have the new ecu installed this weekend in order to ensure it likes the HEI's tach signal and voltage source before I swap manifolds and start tuning. I only wish my old 80 exhaust manifold had an O2 bung on it, as I'd like to see how the old carb fairs for mixture ratio.
Can't wait to clean up that engine bay of extraneous wire and relays.
