Builds The Architect's '77 FJ40 (1 Viewer)

[GA Architect]

I finally got around to removing my rear wiring harness and installing the new modified/upgraded one.

Old:

Bird nest some PO created installing a trailer plug connection:

My new harness with a built-in trailer harness connection:

Note, due to the rear combination lamp female connectors are not available, I upgraded to the Sumitomo DS 250 sealed units.

Nice work. Did you add a white/black tail light ground into harness to tap into solid ground inside engine compartment?

I’d let you work on my stuff. Beautiful.

Being my FJ40 is a '77, the OEM rear combination lights do not use a ground. They are grounded to the frame by the two mounting screws.

However, there are two grounds in my specialty built harness. One of the grounds is for the fuel gauge (& seat belt warning light), which is an OEM circuit, and the other is for my Trailer harness connector. Both of these grounds connect to the frame.

The harnesses I built all matched the OEM part number #82420-90318B. This harness did not incorporate a common run ground through it.

The screws as you know are a poor ground. Wire works Mo Betta

My 1976 FJ40 rear OEM harness #82420-90315 had seatbelt warning and fuel sender frame grounds but added 5th wire ground to tail light. See post #31 for anyone who follows your thread and wants to add ground.

Rummaging thru my parts stash, I forgot about this jewel, 27020-61022-84, 12V - 50A unit I had it rebuilt in 2019.

The current alternator is the OEM 27020-61012, 12V - 40A unit I had rebuilt in 2014.

Not that I had a huge problem losing power to the headlights or heater at idle, but there was some. Soooooo, with a few minutes to spare this past weekend, I installed the 60122-84 alternator.

I’m making a punch list for my Sniper Install and I’m using the same Mr Gasket manifold adapter.

Do you recall what size cap screws you used to attach MRG adapter to 2F manifold?

I assume they are M8 x ?

Thanks in advance. AR

I've installed some new CCOT seat belts, Procar seats, OEM gas tank, OEM fuel filter, new fuel lines. Most of this can be seen in this thread.

Procar seats:

where can I get the cap to go ontop of the sending unit?

If you are talking about the plug/cap on the fuel cover under the passenger seat, it is discontinued.
For a replacement, see post #1,669 -> click here <-

Also, I believe Vintage TEQ Parts may have a plug/cap as well. @ToyotaMatt

Thanks Rick …

It's catch-up week and I'm going to take a stroll down your thread.

 

[GA Architect]

Thanks to @ToyotaMatt , I changed out a few special connectors and made two solid state backup Voltage Regulators for my '77.

Now the two solid state VR's match the OEM unit below.

X2…….. Rick is awful lucky I don’t live a little closer to him!

I had forgotten how distinguished your TLC looks. Bravo sir, Bravo.

I've read and re-read your post(s) REF: Holley Sniper Installation, with more than just a passing curiosity. Your tactics, techniques and procedures are "bookmarked" for future reference.

Applause, take a bow, curtain comes down...

Brother, you happen to go the Sniper route, you will not be disappointed! With all the threads in the past few years discussing the various installs, methods, procedures, parts, differences, configurations, you can bet any issue has been more than likely covered.

Old men and molasses move a little slow in the wintertime.

Wanted to revisit some of the “Sniper” installations as I’m gathering parts. Spent 2 cups of Java reviewing your issues/solutions. I’m certain I’m going to use the Holly integrated regulator and run the dual lines. It works, looks good and it’s there. Also, according to the distinguished forum, the Walbro 392 is a solid unit with a proven track record. Who am I to buck the hive on the Walbro..

I did notice that your 02 placement was a “little vertical” compared to the Holly recommendation. Was that just a fitment problem, IE room? Any other issues flaming your 02? I was pilfering ideas off of @wngrog earlier and thought the 02 heat sink bung extender was a common sense approach to preventative 02 failure. I’m going to steal that idea too and claim victory.

Again, inspiring thread. Now I’m going to go nick ideas from someone else..

Brings to mind an old quote: "He who steals from me, steals from another." Why reinvent the wheel.
