I just noticed a melted connector for my #2 oxygen sensor now that I'm working on the exhaust for my build. The connector is from my 1999 4Runner donor engine. I actually need both sides of the connector but I have a feeling I'll have to buy a new sensor to get that side. Hopefully not. I'll...

I recently purchased my 1980 FJ40 - non US model. After the first day or two of driving - testing all the switches etc - my head lights would not turn off. I have learned the headlights are connected to both the turn signal/ high beam and hazard switches. I have isolated the issue by removing...

2013 Land Cruiser w/ 150K miles. No modifications or changes in the last 2 years, but vehicle has dual battery set up, aux lights, winch, etc. Have a strange issue that started 2 months ago. Truck unlocks with key fob, get in, press brake, push the start button, everything lights up, A/C comes...

As stated in title, the driver side door on my 1999 landcruiser has a lock/unlock switch in which the lock function is not working and has no response. The truck is 99% stock other than a replacement engine. Attempts: Replaced door lock actuator driver side door (resolved weak lock/unlock when...

I live in the Austin area and these 100+ degree days are taking a toll, not just on me but on my cruiser it seems. Door actuators have zero problem in normal temps, but if the truck is left in direct sunlight on one of these days, they develop a mind of their own. I’ve also noticed that the...

I found a project 1991 FJ80 that was local and at a good enough price that I picked it up. The PO had purchased it as a project for him and his son to work on with the intent to use it for light offroading, but it seems that they only made it as far as buying new wheels and tires before the son...

I’m putting an electrical component into my 80. For the purposes of my question, it doesn’t really matter what it is. It has a plug, with two spade connectors. (I’m installing an AC compressor modified to be on board air compressor) I have an ohm meter, but not sure I can use it for much, other...

@Engineer8000 Hello sir. Got a note from @orangefj45 that you were working on a some cool electrical stuff. I have been just starting the same type of work and thought it would be great to sync up perhaps and I could learn form your experiences. I've been testing some old MAFs for him and few...

Can anyone provide help identifying the electrical connection on top of the heater unit (interior behind dash). Not the taped one. I took lots of pics and labeled lots of parts to ensure I put everything back together properly but I must have missed this. Thanks

Good Morning Folks! I'm having a starting issue that's driving me crazy, and maybe you fine folks with your big brains can help. I cannot start my truck (RHD, 1HD-T) with the key. I can sometimes (50% of the time) start it by connecting a jumper wire from the LH battery (+) to the starter (via...

A few weeks back I tried to start my 97 LX. Has dual batteries and both were dead after the vehicle had been sitting for a few weeks. Tried charging them and still nothing. So, tried jump starting it. Still no start (just clicking). Should mention at this point, I had sufficient power to operate...

Anyone have any insight on adding electrical to the starter system? My switch panel has m10 lugs on the main wires but the terminals on the GX are m12. I ordered several battery terminal expanders on Amazin but their all huge and most don’t come with a cover. I don’t really want to go without a...

Specs: 1975 FJ40, 2F, mostly stock... Wiring issues!!! Original wire harness. I am changing out my old taillights and can't seem to get them working correctly. When I hooked them up, the brake light would blink and the turn signal would stay solid. I've switched the wires around following...

1972 40 series that has had intermittent starting issues, now won’t turn over at all. With the key on accessory and “on” the radio comes on. When I go to turn it over in the “start” position, I get nothing- no clicking , no crank. Battery is good, I’ve replaced the battery terminal connections...

Newbie here: I have searched the forums and cannot really find anything similar so I figured I would post here. Last week I noticed that my voltage gauge would dip slightly at lights and stop signs, occasionally going as low as 2/3 before rising back to just below the 3/4 mark. my first...

Somewhat successfully followed the 24 volt removal thread. 1; removed the 12/24 relay, deleting the whole second battery altogether for now (running a wire from LHD drivers main + to fusible links on other side; RHD battery not connected at all for now, planning to change that later) 2; added...

Addressing some nitty gritty wonderfully tedious replacements and deep cleaning of tailgate/hatch and doors this morning and came across a some things I had a few questions about. the photos have text too But 1) what is this black wire? It wasn’t plugged into anything inside tailgate 2)...

I took my ’85 fj60 to a tire/brake shop today to have a flat checked to see if it could be repaired. I handed them my keys for them to drive it around never guessing they’d force my ‘86 Camry key that was on the same ring into the ignition, turn it with pliers and burn out my starter. When they...

So this issue popped up when water entered the driver side dash and caused loads of electrical issues, most of them have been solved but the thing that’s driving me nuts is the car won’t start on main tank “sometimes”. Meaning, if I crank the engine, it starts, and the tachometer goes above 1K...

This one is a bugger, new battery month ago, and seems a bit different than the EFI fuse/fusebox "crank/ no start" issue - old battery was about 3 when it died - Big Interstate Group 31 AGM (little odd so short lived, but I live in the tropics and do low miles). Hopefully this is all some kind...
