I have something exactly like that on my C10 - it's just a distribution block where one small lead comes off the positive terminal of the battery, and a few small leads leave to power various things. I'm leaning towards coolant temperature sensor.

I think it is a coolant temperature sensor. It looks like it's located in a water passage between two combustion chambers on the head, which is certainly a place you would expect to find one. Wouldn't the knock sensor be on the back of the block as opposed to the side of the head? E: 14, you better clean up the gasket faces on those exhaust ports, the one on the left looks rusty as gently caress. Fermented Tinal fucked around with this message at 23:21 on Dec 1, 2016 |

First of all, need wire color codes for all of those if they're not visible in the pictures.14 BAR RIFF posted:I'm in totally over my head on this wiring. I could swear that on a 93 Roadmaster with the same engine, this is mounted to the right front inner fender near the battery. Those are fusible links coming off of it. Not sure what they all do or go to or went to, but it's part of the 12V power distribution system. 14 BAR RIFF posted:Near pass through. 14 BAR RIFF posted:Same 14 BAR RIFF posted:Also near pass throughh 14 BAR RIFF posted:Drivers side block can't locate a matching connector 14 BAR RIFF posted:Near alternator guess: AC compressor clutch and high pressure shutoff sensor maybe, but double check the wire color codes against a wiring diagram. 14 BAR RIFF posted:Goes into harness near distributor 14 BAR RIFF posted:gently caress if I know

Wiring is loving easy if you are methodical and (maybe) label poo poo as you are taking it apart, though that is optional. If you go in with a boltcutter and an angle grinder, it usually does not go well trying to figure out how to put Humpty Dumpty back together.

For future reference, this is what a wiring harness should look like after it's been removed from a vehicle.

I think I almost enjoy wiring more if stuff isn't labelled as long as I have access to the correct wiring diagram with colours labelled on it and a multimeter. Its like a grown up puzzle where you have to match all the colours. Its easy if you are methodical. You are only worried about the ECU related wiring right? (so lights and other poo poo is using the original loom). Get the correct ECU Wiring diagram with the colour codes on (like the one posted on the gearhead-efi.com site linked earlier). Work through all components and identify their wires by the colour codes. plug them all in and then route and cable tie the loom up as you do it, working back from the ancillaries so you have a bigger and bigger bundle of wires towards the ECU. I'm used to doing this on euro cars where all the colour codes are not in English. It looks like a piece of piss using those GM diagrams..

Yeah it sort of did but I wanted to eliminate the miles of van harness that would have filled the entire engine bay. I'm far more confident looming it fresh now than I was spitballing. Current list of un sures: Alternator has one large red wire off the stud post, is there any other connector that goes to it? I feel like there should be. Wiring to this sensor that cracked. Low on passenger side of block into oil it appears.  Single red/black splicing into another sensor on the bracket by the throttle body that also has red/black  Single white from coil  Single green splicing in with wiring to ....temp sensor? By thermostat  This looks like everyone back here

Alt usually grounds through the engine block, actually. Sometimes they strategically locate a block-to-battery or block-to-frame ground cable near the alternator to reduce resistance in the charging loop, but not always, for example: subaru EJ family14 BAR RIFF posted:Yeah it sort of did but I wanted to eliminate the miles of van harness that would have filled the entire engine bay.

I don't think TBI has a crank position sensor now that I think about it and I'm pretty sure the cam position sensor is built into the distributor.

Its got sealant on the thread so it goes into an oilway. quote:Single white from coil quote:Single green splicing in with wiring to ....temp sensor? By thermostat Remember that it isn't unusual to have two coolant sensors. One for the ECU and one for the dash gauge. In my experience the dash one has always been up by the thermostat and the ECU one is often in the block.

Pipe thread into the water jacket RH side of the block, just ahead of the starter and dipstick and just above the oil pan flange is indeed a knock sensor on these and it sure af looks like every GM knock sensor I've ever seen. hosed up place for it but that's what you get slapping EFI on a motor from the 50s as cheaply as possible.

I stand corrected then. RIP knock sensor.I've never seen a pipe-threaded knock sensor (just the donut shaped ones you bolt to the engine), nor one into a water jacket. loving GM

Nice one CSB! I'm wrong too - what a weird looking sensor. Knock sensor confirmed by the images here http://www.troublecodes.net/pcodes/p0332/ which show the exact same one as you have I bet GM just reused a pre-existing hole in the block casting which ran an oil sensor on an older revision.....

I'd just like to go on record and say that I never cut any of the wires unless I absolutely had to. (Looking at you injectors) That big fat purple wire that was cut, that also ran down to the starter on the 350. I think it's still attached on the other end, not sure what you'll need for the new one though. I've been walking Dave through this over FB. I did take some pics, but I tried to keep the wiring harness intact as much as possible, since it's really not all that complex. Each connector and socket is individual so it's pretty easy to match them up. On another note, if anyone's still interested in sending care packages to Dave, any donations of gas money would be greatly appreciated. I know he posted his paypal address up earlier. I've been trying to support him as much as possible here, but the money set aside for this project is almost at an end.

That purple wire being the starter solenoid drive wire makes a lot more sense than it being for the AC compressor. I was wrong again

Tomarse posted:Nice one CSB! It's not an oil sensor location. It's the pipe thread plug that you pull to drain the water jacket. There's one on each side of the block, and have been since the 50s. I like to put a petcock on mine; makes draining easier. They pulled the plug on one side and installed a knock sensor there. Probably was just a convenient place right next to the cylinders.

Can confirm thats a knock sensor. Its a dead ringer with the ones I yanked out of my avalache's 5.3. You can probably run without it (I did for 2 years), just keep the timing conservative. Also, on the ls based motors, they are threaded into the valley pan. Under the intake manifold. I'm glad I listened and bought both sensors and a new harness to do that job. Also, I'll happily offer to look poo poo up for 14" while at work. I can pull up wiring diagrams easy enough, take pictures and send to him.

They build engines the same way that the government commissions military honors? Once they work through all of the surplus gears and Purple Hearts, they can work on new designs, otherwise they might lose pennies on the dollar of a decades old transaction

Yeah, I've got the cash set aside for that, but things have just been getting expensive lately. The bus tickets cost more than I was expecting and constantly buying new parts and shipping them adds up fast. That and trying to keep $1100 or so set aside for tires and stuff. I'm bugeting for about $400~ or so. It took about $300 to get out there, so I'm sure with the new c setup it'll probably suck a lot more gas.
