    This applies for a 77-79 caprice also. Purple is starter signal, pink for hei coil will be your pcm switched power, both reds I put to the starter power lug where the battery cable goes. Wire your fuel pump and it’ll fire no problem

Check this one out... ua-cam.com/video/6SKcYIaHb78/v-deo.htmlsi=RV13tLxq2BL-pEOU We installed a FiTech system on this 87 Blazer, but Jerry talks about the wiring for an LS swap and how the 87's are a little different that previous years.

    Although, Im aware of which wire goes where in a LS swap, I wish you had ended the video where you would connect each of those red and pink wires to the LS harness/relay, etc. That would have clarified any ambiguity from testing between wires of the same color. Otherwise, love the channel and content, look forward to each video.

    • @UglyTruckExperience
      @UglyTruckExperience  6 місяців тому +1

      Hello Nightshift. You don't have to run it through a relay. If works nice when using a donor box and harness but most standalone harnesses that we have seen just have the starter wire going to the starter solenoid with no relay. Thanks for watching. Jerry and Emily

    Much better and easier way to test for these things is to simply use a test light - with an incandescent bulb. I cannot stress how IMPORTANT it is that it has an incandescent bulb. Test lights with LEDs? Throw them away, they're useless. For example, the wires you were concerned with applying +12v to? Simply use a test light connected to +12v. If the bulb lights brightly, it's a straight path to ground. If it lights dimly, it's in circuit with something to ground. The bulb acts as a fuse also, and will blow if you somehow make a big mistake (protecting the circuit), but will generally just light normally if you're connected to ground. You can also connect the light to ground and test for positives. The incandescent bulb will also give a much more... "real world" reading than a voltmeter. A test lamp's incandescent bulb will put an actual load on the circuit, and won't light brightly if there's a significant resistance or poor connection in the circuit... where a voltmeter might read a perfect 12v despite such a problem with the circuit.
    They're just more versatile tools in general.

    • @UglyTruckExperience
      @UglyTruckExperience  Рік тому +2

      Thanks Madman. This video was an attempt to show someone how to test these circuits without having a battery source just yet in their project. A test light is a great tool if you have a little bit of experience. Many people would look at a dimly lit test light and think everything is fine. There are thousands of people out there doing this for the first time and for them a lit test light is a lit test light. For people that aren't that experienced there is no better way to learn this than using an ohmmeter and recognizing a problem in that circuit. We appreciate you watching and commenting.

I have an 83 trans am I'm wanting a 5.3 and a 4l60 put into. I'd like to talk to you about if you would be interested in doing this swap for me.

    Question, I rewound the video and there were four wires laying on the fuse box in the beginning of the video. In my vehicle, I found three wires, pink purple and red. None of the other wires seem to be large enough. How do I locate the other large wire? For reference my vehicle is a 72 K5 that has been rewired by a previous owner...then it caught fire, a small fire, so I bought it cheap.

    • @UglyTruckExperience
      @UglyTruckExperience  Рік тому +1

    • @UglyTruckExperience
      @UglyTruckExperience  Рік тому +2

      I looked at a wiring diagram and also looked at our 1972 truck and It also only has one power wire leading into the cab for the interior fuse box. I would check that one large red wire you have for continuity or a short to ground since there was a small fire. If wire seems good. Put battery voltage to it and test that everything is working properly. Hope this helps. Let us know how it goes. Cool truck also, I wish I had one.

    Question. Putting an LS in a 1961 Pontiac with generator wiring. Obviously I am eliminating the original generator and voltage regulator. There is a large yellow wire at the horn relay junction post from the battery fed by a large red wire. Another heavy wire went from there to the original starter. That yellow wire goes into the fire wall directly to the amp gauge. Then a red wire comes off the other side of the amp gauge and splices into several red branches the under dash harness feeding everything under the dash, and also comes back to the voltage regulator on the outside of the fire wall. I am thinking the I can eliminate the red wire that comes back out to the voltage regulator from the place where it branches from the rest of the red wires to under dash. And I can feed power from the LS fuse box to the Yellow wire that goes to the amp gauge . There are several possible locations to do this from. an ABS 60 fused plug on the underside and a couple 50 fused plugs also on the underside. Or there are two posts on the corners of the fuse box that I could use and possibly put a 50 or 60 amp fuse into one of those. Do I have the right idea? Any recommendations? Will my amp gauge work still?
    Then All I need to do is connect my purple ignition starter wire to the C1 -A3 terminal, and my ignition on wire to the C1 - A9 position. Correct? I will also eliminate the old coil wires from the ignition switch that you mentioned in the video, correct?

      The Amp gauge should work with the wiring you described. I think your power wire for ignition will go to c1, position c9. Your message said position a9. Double check that in case I am wrong. Sounds like you are on the right track though. Sounds like your close to firing it up. Let us know how it goes. Jerry and Emily

      The starter and ignition on wire would be the same pretty much. Everything else would be different. We use Alldata for our diagrams. They do have a reasonably priced program called AlldataDIY. On older truck wiring diagrams, LMC or Summit has a bunch of the older ones. Thanks Shaun. Jerry and Emily
