So a few weeks ago I purchased a new taco plate and temp sender from FAT performance. I thought I'd need a new one for my other motor anyhow. Well, found the culprit. The wire in my engine bay just broke. That's why my temp sender read 0 the whole time. Two connectors and some heatshrink later, I've got a working oel temp gauge. Yay.
Now to get the Weisstach setup with 1 temp sender per head. That'll replace my clock alright.
