I used the MilSpec connectors (3) for 12 dual plugs, 6 injectors, assorted sensors.
The Crank trigger I left it direct, without connector, to avoid any signal interference.
I used Pro Wire as my source (prowireusa.com) and used Tefzel wire (much smaller and fits a lot of wires into a small connector)
I used Weatherpack for all other connectors for power block to the ECU, etc...
Here's my setup showing one of three used. In the end, I needed to make the legs a few inches taller. Pulling my engine takes 45 minutes (using a lift).
