Guys,
We just completed a built L18 / 5 speed conversion into my brother's 79 1200 ute, and we have a couple of problems I was hoping those in the know could help us with.

1: The coupe looped tacho is wired up as per wiki info, (please see pic) and all we get is some very slight jumping around every now & then when the engine is running. - The tacho wire was the wrong way around (to "-" trigger) & I changed that when I checked it as per the pic. - Any ideas?

2: We are using the early skyline stumpy 5 speed, what model dato do we pilfer a speedo cable from to get the factory 1200 speedo working correctly?

Happy with the build, we are running the engine in but can tell it's a huge improvement over the worked A14 that it had previously. - Much more torque. The L18 was rebuilt with Hypatec pistons, 10.5:1 comp, Anothony Koch spec'd cam & a good port & polish. It's running a jetted down draught weber we had laying around until it's ran in, which will be swapped out for a single 45mm side draught.
