wiring

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...

I recently removed my intake manifold to replace the manifold gaskets. Anyhow I put it back together and now the oil pressure gauge isn't working right. I can't remember how I took it apart as the project spanned many weeks. I have these two plugs left over. One is 24v the other might be...

I recently bought a Baja Designs S8 30" light bar for a C4 lo pro front bumper. We installed the bumper, winch, and light bar this past weekend. My switch for the light bar didn't make it in time , so we wired everything up and pulled the end into the cab for the switch installation later. The...

as the title suggests, id like to try to replace/upgrade the factory amp located behind the front passenger glovebox in my 80, rather than bypass it with a new head unit. (i just really like the look of the old school 90's head unit and don't want to change it- also i like the two little...

Hi all i am rebuilding My 80 from the ground up. Complete refurbishment and modernization down to last bolt and nut. Thread coming soon. Separate engine thread already going. as I want a standalone system for the engine, and I want to simplify all the other wiring in vehicle using PDM’s instead...

I recently bought my 105 and found some wires disconnected on my transfer case and engine bay. I don't understand what they're. Please help to find what they're and how to connect them properly thanks

Hi guys putting a internal regulator alternator in my hj60 i know what wires go to the alternator from the regulator plug but is this the right way to bridge the rest of the terminals on the plug

IH8MUD Team, My 76 FJ40 (completely re-wired about 2 years ago) started having the below issues recently, I believe simultaneously and all of a sudden. Wondering if you can suggest where I begin looking to identify the issue as I assume they are all related. REALLY don't want to take it to...

Editing this thread so my stupidity doesn't confuse someone else who stumbles upon this in the future. 1996 Lx450, 152k miles, NO front or rear lockers. CDL Dash Switch, Pin-7 Mod. 4WD High and Low work fine, but the CDL hasn't locked since the day I bought it. When shifting into 4WD Low, or...

Recently swapped a 2H into my fj73 and im just trying to figure out the alternator wiring. From what i understand there is a three wire plug (green,blue and black). One is the lamp one is the ign power and the other battery sense. Is this correct? Can anyone confirm which wire is which? And the...

Alright wiring guru's, who's up for a challenge?? I've got a good one here! 2002 Toyota Land Cruiser, 151K miles, I had just filled up and after starting the car the radio starting spazzing, the dash started spazzing as well with needles moving all over the place, and all of a sudden all of the...

One of the small luxuries I gave up when I took ownership of the 80 was wireless central locking... Until I bought a $20 wireless receiver to actuate the keyed central locking from a distance. As I was going about installing it I went to search for a wiring diagram and found it more difficult...

I have just completed switching out my '96 80 DS door with a used '94 DS door. I hade wrecked the previous door when I rolled it on it's side in Borrego. There are two wiring connectors that travel to the DS interior. The larger one matched both doors. Oddly enough the smaller wiring...

Hey All! Here I am dinking around with ecu wiring due to o2 sensor shenanigans after a long-tube header install.. I can't find ox1b or ox2b at the ecu and the pinout instructions(second plug, 21 and 29) that I do have are not correct. Those were related to knock sensor territory. 🤔🧐🤯 Stuck...

Gday all, so I’m a 3rd year mechanic apprentice doing a 1fz swap to a 1hz. Mainly because I’m gonna be touring so I want a diesel for that. Have the engine ready, but no harness. Just wondering if and what is needed for a 1hz engine loom to go in and what I can reuse on the 1fz. It’s a 94 GXL...

Howdy! I recently purchased a December 78 and it has some interesting wiring (I know, I know, they all do). Currently I have the battery out while I am baselining the truck and when I put it back together I don't want to A. Fry the new stuff and B. I want to put it back together "correctly"...

Just received my new SpeedHut gauges from @FJ60Cam at Mosley Motors. They look AWESOME! I think I have the SpeedHut lighting inverter and the "main" wiring figured out, but I'm worried about this yellow sensor wire to the tachometer. There seems to be a corresponding yellow wire on the OEM dash...

Hi folks, just got the Redarc delivered and inspecting how to connect it to the 2021 LX570. Where does one connect the Green (headlamp switch to vehicle tail lamp) on the RedArc, if at all? Thanks! Diagram:

So my LX will randomly turn on the wipers by itself. This issue appears to be totally random. Im leaning towards something being shorted somewhere. Has anyone experienced a similar issue? I desperately need to get this resolved as its super annoying and embarrassing when my rig decides to act...
