This is a picture of the fittings I recieved today. I can't say how impressed and pleased I was to work with
Fittings and Nipples
I ordered my parts late Tuesday night, received a shipping confirmation email early Wednesday morning, and received the parts via UPS today (Thursday).
You can see I only needed to buy two 1/2" nipples and a 1/2" Tee. The autometer sender came with a bushing adapter that connects the sender to the middle of the 1/2" Tee.
Now I just need to figure out which line is the line leading from the trans to the cooler and splice the Tee in.
Then I need to figure out the wiring. I have never spliced into a fuse box to tap power like someone did earlier in this thread so I might be back with some questions.
