aftermarket tach install

I'm trying to install an aftermarket tach in my 84, but can't get anything out of it. I have it grounded to the dash, the red wire is hooked to the only terminal marked "IGN", and the green wire is plugged into the terminal on the cap marked "TACH", but no luck. I was told on another site to tap into the white wire coming out of the tach port on the cap, but that only goes to the plug for my ac compressor. There are 3 other wires coming out behind the white wire: Brown, Black, and Pink/Red. Do I need to tap into one of those to make the tach work? (I can't post a photo of the wires as the photos are to large.)

Serpentine Belt System Recommendations

Any thoughts on the best complete serpentine system to use? I initially thought about just getting a stock junkyard system, but I really don't care for the looks. So, I'm pretty much only considering an aftermarket setup.

There's the Holley mid-mount system

There's March

CVF racing

Blueprint has a system now

Am I leaving something out?

They're all pretty much in the same price ballpark. So, I'm thinking looks could be a deciding factor. But, I'm thinking about replacement parts. What if the waterpump fails? A replacement from Holley is about 400 bucks. What kind of pump do some of these other kits use? Do they just use a kind of generic reverse rotation pump that I could find just about anywhere?

? Fuse Box Firewall Conn Wire Problem

April 13, 2021, 09:52:28 PM by Mike81K10

I have a Pnk wire for systems 30 that was loose (with a female terminal on it) at one end and terminates at the instrument Gauge connector (plug) on the end where two pink wires are located on the same terminal (the other pnk wire is a loop).

Then there is a pnk with black strip systems 39 wire connected to the fuse box inside cab firewall connector and it terminates where the wiring diagrams say the pnk wire systems 30 is suppose to go (believe it was like this from factory). This pnk black strip wire terminates to a splice in the harness about a foot from the firewall connector.

I am doing right by connecting the pnk wire system 30 to where the Pnk black stripe wire was (according to the wiring diagrams) and by moving the pnk black stripe wire system 39 where the diagram shows, it puts pnk black strip wire in a spot where there is no male terminal on the engine side of the firewall fuse box connector.

All the other wires check out in these two systems according to the diagrams.

My truck of course is a 1981 Chevy K10, 350 Engine, original engine was a 305. Did not have A/C, however I am installing A/C. Has Gauges!

Hey guys.
73 c20 here.

Have a squeaking noise when I accelerate and I'm thinking it might be my fan belt.
What do you think?
