Bit of an update.

For the GPS, so I can hear it over my sound system and glasspack, I've added a small amp and a set of speakers.

The amp is a previous version of this: https://smile.amazon.com/SODIAL-PAM8...dp/B07KVYKRHN/

Speakers are a pair of BOSS 3.5" speakers, like you'd find in the dash of a 70's GM.

They mount to a 4x10" mounting board, like https://smile.amazon.com/Best-BKUSB8...dp/B00Q507S4A/ .

That board (that's the one I bought, BTW) took a couple of small mods. 1) You have to notch one side, above the mounting boss, to clear the tab for the interval wiper controller mounting bracket. Wasn't hard, just cut in and up to take out the sloped part.

2) You also have to enlarge the mounting bosses a bit; the studs on the dash are 10-32 so the #8 holes are not quite big enough.

I used four long 6-32 bolts to mount the speakers to the board, and a pair of nylon nuts to mount the amp to the inside hole. I also mounted it with the volume control pointed DOWN so I could adjust it without having to crawl all the way back into the truck.

Works good.

I've got some whine due to a ground loop; I've got a MPOW isolator https://www.ebay.com/itm/Mpow-Ground...m/142521451590 coming to break that.

Oil pressure now indicates with the new connector on the wiring harness.

Don't know why a 30 year old truck with almost 400,000 miles on it would have connectors failing with age ...

The hits keep coming!

2 year old radiator cap started spewing today ... grabbed a cheapie from O'reillys.

But I also ordered this: https://www.ebay.com/itm/322380145945

I mean, why not?

$36!!! But that is darn cool.

 

That is neat. I take it reads coolant temp? I would love to see what that shows system pressure.

 

Pressure would be nice; it's got temp instead.

But that's OK.
