Re: Restoring Rusty
picked up a couple of these plastic storage bin organizer thingies from Harbor Freight, they are normally $14 bucks but I found a coupon for $6, now I gave up on Harbor Freight tools a while back but I figure they can't screw up plastic bins too much, LOL
now maybe you can relate, I struggle organizing car bits, like fuses, washers, butt connectors, light bulbs (why do they insist on selling us two when all we need is one) nuts and bolts, cotter pins, etc, it seems like every little thing needs their special nook to live in, so there you go also from time to time I just stand in the middle of my Temple (some call it a Garage others a Workshop) and I say why can't I find the altar, where did all this junk come from, where am I to rest by beer and I take a moment and I try once again to get re-reorganized |

Re: Restoring Rusty - Engine Bay Pics
mounted the driver side inner fender today and figure I'll share a few most recent pictures (yes I said pictures and not pics, I speak 40+ year old, LOL) of the engine bay, with the inner fender and them purdy (for a while at least) long tube headers, oh and the painted frame rail
not back for a blond Pollack if I do say so myself, but we're not there yet... Last edited by Gregski; 05-21-2015 at 01:48 PM. |

Re: Restoring Rusty
Wow, Greg, what a difference! Those inner fenders look great, considering the low-buck approach you took with them. Radiator core support next?

Re: Restoring Rusty
and so operation Tach You're It commences
there are three things to carefully disconnect before removing the gauge cluster 1. disconnect the mechanical speedo cable (cable looks and feels like the brake cables on your old 10 speed bicycle) 2. disconnect the mechanical oil pressure gauge by unscrewing a metal tube from the back, first undo the three screws that hold the gauge and pull it forward a bit (why it's called mechanical I don't know, it should be called hydraulic) 3, disconnect the thin ribbon cable that goes to one of the light bulbs, it may be an additional ground strap |

Re: Restoring Rusty
then we are left with some ugly cobra looking wiring harness
which for all intensive purposes we must study and learn, so here is the front side of the connector Pins #1 through #9 and their respected colored wires, we shall call this poor man wiring diagram side Uno |

Re: Restoring Rusty
ok, so far so good, but here's where it gets interesting, I noticed that three wires loop from one side to the other, so wrap your mind around that for a minute
looks like the pink wire, the tan wire, and the tan/black wire are playing both sides (politicians are they) |

Tan should be the fuel sender. GM wired the harness for both large and small fuel gauge. You'll have to change terminal positions for the 78 cluster.

Re: Restoring Rusty
ok folks put on your detective hats because we have a situation, there is a lonely loose black wire it disappears into the wiring harness and appears to be headed towards the cluster connector, we must track it down

Re: Restoring Rusty
ok, it appears the black mystery wire splices into another black wire that plugs in to Pin # 9 ie Ground, fair enuff, now we need to figure out where it was headed the other direction does it go to the fuse box, or screw into the dash somewhere?

Re: Restoring Rusty
1974 used a sheet metal ground for the main cluster ground wire. Sounds like the cluster Ground splice gave up the ghost.

Re: Restoring Rusty
Are those the black wires for your ammeter that run from under the hood? Run a test with your voltmeter to test.

Re: Restoring Rusty - Oil Pressure Gauge Upgrade
so one of the side perks of upgrading to a 1978 gauge cluster is that it has the electronic oil pressure gauge, so out with the old mechanical one first
the mechanical setup has a metal tube that runs from the back of the engine block under the distributor by the firewall and into the cab, and connects to the back of the mechanical oil pressure gauge, yes oil goes way up there into your dash and could possibly spray you in the face @ 60 PSI awesome - NOT! |

Re: Restoring Rusty
Maybe the black could be seat belts ?
Among everything else grounded they usually went down to one wire about a foot from the cluster plug in

Re: Restoring Rusty
Thanks, so in '74 there is no 6 prong bar, that came later? I don't have one so I don't know if I am missing one or it never had it, thanks
