My 72 was converted to carbs long before I got it. I want to go back to fuel injection and have an L jet from the 75 1.8 engine that's in it. What does it take to convert the 72 to the L jet set up?
Thanks,

All of the relay boards on 914-4s are identical.
The L-Jet system does not use any of the relays on the relay board. L-Jet uses a different engine harness from D-Jet. It has a double relay connector coming out of it, and one extra yellow wire that comes out of the engine harness at the relay board. It plugs into one of the two rear most connectors on the 4-Pin connection at the left rear of the relay board.
So use the engine wiring harness from the 75 and you will be fine.
Hope that helps.

Yes, that's what I needed to know. Thanks!
