I need to finish up the install,I am currently attempting to install the adapter for the freeze plug hole. I am frustrated by the huge wiring harness going above it. I can not get the adapter lined up with the hole nor can I attempt to tap it or put on the hose extension without it pinching. PLEASE can anyone tell me how they dealt with this damn wiring harness. What was your procedure for installation in detail for this adapter? How did you deal with the harness? Please help ASAP,she is sitting out in the rain.
