Fantastic job Andy!

It seems as if all the TJ-07 guys have wiring down to a science. I'm wondering why you didn't go with two loops especially with two radiators?

Also, you said you found BSPP elbows? I could only find BSPT male/ BSPP female 90 degree elbows at Mcmaster rather than the optimal BSPP male/BSPP female elbows.

Do you have the part number on hand?
