    O2 sensor woes 7.4 B2 S1 and B1 S2

    I am using my scanner to read. Bank 1 sens 1 works fine, so I am going to see about swapping that sensor over. I was hoping to do that as a last resort as I think it's the original sensor in there and I had a hell of a time getting Bank 2 sens 1 out lol.

    O2 sensor woes 7.4 B2 S1 and B1 S2

    Hey guys, I am trouble shooting a dead O2 sensor on my 98 7.4l. I swapped the original OE one with a bosch one and it is still showing that it is dead on the live data. I am getting bias voltage on B2S1. I verified that I have low resistance between the ECM connector and the O2 sensor...

    98 7.4l wiring harness bracket that mounts to intake manifold

    It isn't really too complicated. I could try bending something with heavy gauge steel, but I would rather source it off a junk engine. I just have it jerry rigged with zip ties right now to keep it off the EGR tube, which has been working fine. Yeah, I have been having a tough time finding...

    2nd horn location

    I am working on installing the 2nd horn on my 98 c3500 7.4l. The service manual shows 2 mounting locations. One of them looks like it is using the same hardware as the head light, is that correct? Thanks.

    Unplugged connector 1998 c3500 454

    UPDATE, turns out this is my 2nd horn and it is missing. My horn was sticking causing a constant ground to the relay. Horn was probably blown out from last owner as the 1 horn on it isn't working. Ordered 2 new horns and corrected the horn switch from sticking. My model does not have an...

    Unplugged connector 1998 c3500 454

    Good afternoon, My horn is the last thing I need before I can get my c3500 registered. It doesn't work. I verified that I have 12v constant at the relay and I tried to jump the hot to the other 2 terminals with no horn. I noticed that this connector that is in front of the battery is...

    98 7.4l wiring harness bracket that mounts to intake manifold

    Hey guys, I am looking for any solutions to a lack of a bracket that is allowing my wiring harness to burn up on the EGR tube. Just purchased the truck and noticed that it is missing the bracket that mounts to the intake manifold as seen in this picture. Searching high and low for a part...
