Yep stock thunderbolt. Going to re-wrap my harness's and my dart blocks don't have the provisions for all the oil senders down on the the bottom of the block. So if I have to move the senders to the top-rear-middle of the block, I'll probably go ahead and shorten/clean up the harness while im at it. Was just wanting to loot at wht there are what appears to be two pressure sensors down on the bottom left of my gen 6 block and no place for this on the dart m block.

One sender is for the guage and the other is for the Merc alarm system. The alarm system uses tan wire with blue stripe.

I've got those two cleared up but i also have a third sensor down there. Its a temperature probe but im not sure what its for. Oil i assume, but i also have an oik temp sensor on my filter mount next to my oik cooler. Im just wanting to make sure these sensors get to thr right places in my dart blocks.
