Got an 85 S15. Installed a head unit and speakers several months ago and they’ve been working fine until about a week ago. Seems to be a bad ground. Speakers are weak and sometimes buzzy and headunit dims in and out with the music. I’ve checked the ground next to parking break release but I...

Hello everyone. I’m new to the forums and new to s10s and ls engines, coming from a diesel world and wanted to try something new. I have a 1999 2wd s10 it’s a base model crank windows and the truck does not have hvac (my choice). Engine is a 2000 lm7 engine with minor upgrades.Anyway very close...

Hey guys can anyone please help me? I'm almost done with my LS swap but am stuck atm trying to figure out how to wire the alternator. The 5.3 alt that I have has 3 wires in the plug. One is pink w/ blk tracer, the next is a light brown or tan, and the third is black w/ white tracer. The pink/blk...

Hey guys not sure if anyone has any experience with this but I have recently installed a rearview monitor with backup camera and dash cam setup on my newly purchased used 1998 s10. I wanted to wire this to always be on with my headlights. I know that means it will always be on at night but I...

I am bringing my dad's 1991 s10 back to life from boxes. He just passed and I'm hoping to restore to semi newish, The motor was shot and a used replacement motor was purchased. That's when he stopped. I have installed the motor and I'm working to get the wiring and vacuum all correct. In...

. I paid for and downloaded the ALDATA program and it has been no help. What I am building is a 1993 S10 and putting in a dash from a 1988 that was much better shape than the one that was in there. Also putting in a 350. Grafting the 88 dash to a 93 has been challenging. I did a 1991 S10 that I...

All right guys, so the right side of my turn signals won't work, on the front or back of the truck. Whenever I flip the switch the signal for a right turn, the indicator lights up but does not Flash, and does not click. The left side works fine, as does the hazards. When I turn the hazards on...

2000 s10 was a 4cyl. When I turn on my headlights I cant use my turn signals. My turn indicators light up solid and so does my high beam indicator.

So long story short, I got a 1988 S15 from my neighbor that sat in a field for a few years. I v8 swapped it and now i'm chasing down some wiring problems I'm coming across. -I have no power to the radio or any of the dash ( Dummy lights still work but nothing else ) -My light switch turns on...

Hi guys, My 88' S15 right turn signal will not blink. The front turn signals ( both upper and lower left and right) work just fine. the rear tail lights are all illuminated, and the left tail light actually flashes when I put my blinker on. But the right just stays illuminated like when I turn...

Hey everyone, I just joined this forum and am in need of some ideas. A few months back I managed to get my hands on a "barn find" 1997 GMC Sonoma SLT stepside that somebody has installed a smallblock chev 400ci v8 into with an aftermarket 3 speed transmission (its a 'transco' if anybody has...

I have a 94 S10 4x4 with a 4.3 vin W that took a dump. I have a 5.7 out of a 97 C1500 Silverado to put in with all the wires and ECM except OBD2 port. I'm trying to figure out if I'll need all the wiring or if anything already in the truck will work or any problems I may run into. I've...

A previous owner of my truck (not the guy I bought it from) Bubba'ed the **** out of the wiring. "Interesting" features include the wrong wiper motor without a pulse board, a constant 12V to the sprayer motor (hopefully related), and a doorbell button with an alarm klaxon. But anyway... In any...

I have recently bought a 97 rcsb s10 that has a 5.3 lm7 and a nv3500 installed. The person who done the swap done a bad job to say the least. When they done the swap they deleted all four of the o2 sensors and the knock sensors. I have not been able to hook up to the OBD2 port yet cause they...

Hi all, first time poster and I really need some insight about an electrical issue I am having with my 87 chevy s10. A few months back my dash lights started cutting out. Over time it started happening more frequently until they just stopped working. About a week later I turned on my lights and...

I recently bought an 83 s10 swapped with a throttle body 350. But they changed the throttle body out to carburated. The wires were a mess when I got it but we went through got rid of a bunch of unneeded b.s. Now I've got one problem. For the life of me I cant get the altenator to charge. I've...

So I have a 1991 s10 brake lights worked but driver lights did not when I bought it come to find out where it holds a fuse in the fuse box under dash the prongs that hold the driver/parking light fuse are gone so until I get around to buying a new box I ran a hot from ignition so basically when...

I recently wired my 01 s10 for trailer lights and all was fine. I spliced right after the connector for the whole rear light wiring harness. My lights were working perfectly fine until my driver's side turn signal started hyperblinking and I had no break lights on the same side. I crawled under...

Hey guys, i recently bought a 1982 S10 2.8 4-speed manual, she runs and drives with some mechanical issues that are being fixed (started with replacing that POS Rochester 2-barrel with a Holley 350cfm 2-barrel) problem is.... i bought it from a crackhead for $100 and it has NO interior i...

Sorry if this has been posted before, but all of the other threads I found were non-conclusive. Little bit of a backstory on the truck. I got a 1988 S15 with a 2.5l iron duke from my neighbor for free since it wasn't running. Ended up having a hole in piston #1, I decided to swap out the engine...
