@ZachOrie - I know you said that you had gotten a manual, but these wiring diagrams are also very handy.... they are color-coded with factory wire colors, more durable than paper, and sometimes are easier to use than a book with folded out pages, especially when one is laying on their back on the floorboard, trying to track down some underdash wiring issue.

Hey guys!

Diagnosed the tach: it gets a signal but no power. Tried powering it with a cable straight from the battery and it worked!
So I guess theres a dead relay/fuse somewhere; Thing is I can't find any traces of that red and yellow 12v when I try to follow it behind the dash or under the hood (no mention of it either in my manual, it seems we don't have the same one @LILCBRA).
Does anyone know where is the relay/fuse associated with this cable?

Other fun thing: By getting the tach to work I was able to verify that my engine idles at 2000rpm, not great. :O_o:
Any advice for idle tuning?

Also I started looking at the brakes:
Front discs do something, rear drums do nothing at all.
Opened the rear drums, they're clean and nothing seems off. I guess I should bleed the brakes to see if there's actually some fluid reaching them?
If there isn't then what's the diagnosing process? I mean they've been unused for 35 years so I guess it could just be stuck?

Thanks for your help on those issues :nice:

Definitely bleed the brake system as a start. Once you bleed them i would then look for any leaks along the brake lines/fittings... as maybe they previously leaked all the fluid out. Just a thought.

Hey everyone!
Merry winter, I hope you're doing good! it's been a while since I updated on the fox :) :banana:
I've been working on turning an Oldsmobile Cutlass I had prior into a reliable daily (1982, diesel v8 (yes it sucks)).

Here's the update:

Engine-wise it runs great! Learned things like timing and carb tuning and got it fairly dialed.
It still has an issue where it starves, so I'm suspecting the fuel pump isn't getting good enough voltage or just shouldn't be in the engine compartment.

Cooling system had signs of being bad: it revealed itself not to have a themostat installed and the place where it sits looked awfully dry... I tried filling it with coolant from there and it gurgled fine, so water pump is good and it probably just needed to be primed!

Exhaust fell off. We were planning on replacing the blown muffler with a friend but the whole thing broke (rust) at the dual-to-single junction behind the manifold.
ANY ADVICE ON GETTING AN EXHAUST AND MANIFOLD FOR A V6 MUSTANG WOULD BE GREATLY APPRECIATED.
It seems my only bet is capri/taunus manifolds and a prayer that fitment won't be an issue. The rest will probably have to be custom made? Would anyone have any guru knowledge on this whole thing?

Also brakes! I'm in the process of remaking most of the hardlines, I refurbished the rear drums with new hardware and pistons and also replaced the master cylinder and rubber brake lines.

The bad part is that the car has sat outside and the sunroof ain't looking too good for it :/
Badly bubbled paint and the metal frame of the glass is clearly bulging upwards... Protected it with a tarp but that'll be first thing on the bodywork list...

Probably forgot some stuff but I'll update more regularly :)

Cheers!

You can maybe add the granada to the list of fox body cars that had a Cologne V6? In the US, the granada was a fox car. Manufacturers like to use the same name for completely different cars in different locations, so who knows? :D

Unfortunately not! I think you're crossing two different models :/

1765333761150.webp

^ The US granada is a fox car but never had the Cologne as far I know, only the Essex v6

1765333961592.webp

^ The EU Granada had the Cologne but I don't believe it's a fox car :/

Unfortunately always the half of the whole equation... I don't know if anyone ever tried fitting Capri/taunus/granada headers in a mustang.
I think there's a Cologne guru on the forum if anyone can tag him?

Those grenades (Granada) never got the 2.8
6 pop, 5.0 and 5.8 was it
The Fairmont's were also Fox bodies, and they got 2.3's and 5.0's not sure if any 2.8's made it into them or not
Pinto or mustang 2 manifolds for a 2.8 will work right?
I'd compare those to 1991 Explorer manifolds and see if they will work for your Mustang

I don't know if they'd work since I have the european 2.8 with the siamese ports, also the explorer is a 4.0 cologne so would it be the same kind of headers?
