Anyone have pics of Trailbeasts HEI conversion?

Here ya go.
The ECU can be mounted anywhere you want as long as it has a good ground, as can the coil but it doesn't need a ground.
I mounted my own over by the fender where it's protected from engine heat.
I also used the taller coil.
Same thing just a taller bracket.

Almost for got you asked about the ballast.
If it's a four wire ballast just follow the two wires from it to the harness (behind my coil in the picture) and connect them together with your power wire for the new coil.
You are connecting ign1 and ign 2 together so you have coil power in both the start and run positions of the key.

The short little wire with the blade type connector on it coming off the top of the coil is the tach signal connection and works with most tachs that normally connect to the canister coils negative terminal. (usually green on most tachs)
