    Fuse block. Ignition and keyed power. Help me please

    I have figured out the ignition wires before your response. However, thank you for your response. What I meant by “buzzers” are the door jam switches that sense when the doors are open and closed. These activate the dome light when the door is open. I guess the thing that concerns me is why...

    Fuse block. Ignition and keyed power. Help me please

    I am so confused. I have my battery wire running to the battery from the fuse block. I have my pink wire running to my underwood fuse block for my ls swap. Here’s where it gets weird. There is a little range wire under the dash the lugs into one of the battery slots on the fuse block. It...

    Oil gauge and water gauge question

    Got my wires narrowed down for the gauges. All I need to do now is find out how I’m going to install the factory gauges for the 79 c10 gauges on the ls. The oil pressure sender adapter is easy to find. The water temp adapter however, not so much. The threads in the ls (on the passenger side...

    Oil pressure sender

    I cut the oil pressure sender connector out of my harness because I thought the gauge on my 79 c10 was mechanical. Thought I didn’t need it. Low and behold, it’s wired! Now I have to wire a new up. To be honest, I’d prefer the oil pressure sender to be out of the harness anyways because it wires...

    Ls swap question

    Not to beat you to death with questions. But I have no where local that can do the flash for me. Do you know any reputable places where I can send the ecu? Sent from my iPhone using Tapatalk

    Ls swap question

    Outstanding. I just ordered a new tank and sending unit. Going to order the pump next week... Not to derail, but when I swap the motor, ecu and harness out of the donor, do I need to get the ecu flashed to get rid of the anti theft system? Sent from my iPhone using Tapatalk

    Passlock?

    I am swapping a 5.3 into my square body. The motor, ecu and harness are coming out of the same truck. Do I need to get the ecu flashed to get rid of the passlock (anti theft) system? Sent from my iPhone using Tapatalk

    I’m not sure. I’m going to have to go look. But if it doesn’t then I have to get the regulator that goes inline, correct? Sent from my iPhone using Tapatalk

    Ls swap question

    I have a bare frame right now. All the lines are still connected to it from the original truck. Should I leave these lines and tap into the fuel rail that way or use the lines off the donor? Sent from my iPhone using Tapatalk

    The 87 sending unit has a spot for the pump? Which pump should I use for that? Sent from my iPhone using Tapatalk

    Ls swap question

    Ok. Im trying to use every part from the rails back. The pigtail that comes off the 99 sender has four wires. One of them is for the gauge. My theory is that if you take the wire from the original gauge and tap it in there, it should work the gauge properly. Being that the ohm range is 0-90.. so...

    Ls swap question

    I’m swapping a 5.3 into a 79 c10. The swap/wiring isn’t an issue on this one. I’m just wondering how you guys have gone about fueling options on your swaps. I know you can get kits and all that. My question is this. I’ve got a complete 99 Silverado with a bent frame that is responsible for...
