So the trucks and 84 C10, the engine is a LQ4 but it has the intake from a 2001 5.3 and the engine harness and fuse box from the same. The engine has been sitting for years so I really wanted to hear it run.

Problem is it keeps blowing a fuse labeled SEO IGN. I figured it had to do with some wires I cut, just some going to the transmission and some for the rear O2 sensors. I had taped those up but I figured something was touching and opened them back up already, and nothing was touching that I could see. So I spread them all apart, taped them up and it still blows the fuse.

I didnt remove the wires from the harness yet because I wanted to make sure it worked before I removed anything, but that might be whats ******* me over?

Thanks for the help. I threatened the truck with taking the LQ4 out and Installing a 5.0 I have but that just really pissed it off and all the fuses blew...

I wish to suggest a tool for keyword ranking checker. You may use this tool to monitor and evaluate where keywords are showing up in search results. You must utilize this SEO tool if you want to properly advertise your website or other online resource and grow your business.

Ever figure this out? Im having the same problem. Turn the ignition on and it blows the 10amp SEO ign fuse. Im doing a 5.3 swap so it could quite possibly be something not hooked up or something I missed.

Please let me know if you found out why you kept blowing that fuse
Thanks!
