i by accident bought a pin out JB4 instead of the PNP
i am a little confused.
are there not any clear instructions about wiring the JB4 pinout?
or do i just have to wire it like a JB3 as there are instructions, and then rear the JB3 to JB4 harness modifications to find out which ones i need to switch?

if someone can explain id greatly appreciate it.
ive searched, and asked terry, but he just sends me the 2 instructions that i described above
i want to plan this out before i remove all the covers in the engine bay and pull pins out
