Doing a 5.3 4lx0le swap, please help
 

What parts of the harness do I need to keep and what parts can I throw away as far as just pulling it out of the vehicle

Re: Doing a 5.3 4lx0le swap, please help
 

I bought my engine and trans from a yard and they left the center plug and cut the others as far as the could. If you are going to use the under hood fusebox, you will need the other plugs. If not, they may be useful but might not be needed.

I have been following these instructions and they have been very helpful.

I have my 5.3l running with the under hood box. Takes a lot of the guess work and hack out of the swap.

Thanks for the reply, do you guys have pictures? And what engine mounts did you use?

Re: Doing a 5.3 4lx0le swap, please help
 

I used some engine brackets I got off eBay from kids-performance. They were just under $100 and they fit great. For the mounts I used the cheapest stock replacement mount I could get from autozone.

On vacation right now so I can't take pics. Will try and remember to take some when I get home.

This might seem like a minor detail to most people, but the only thing that I'm concerned about, is the freakin' gauges. Replacing the factory ones with autometer was bad enough in and of itself. Can't imagine how bad it would be trying to get them to work with a whole new engine.

Also, does your truck have AC? Or will it now?

I believe you can use the stock cluster out of a 90-91 suburban k5 and crew cab.The ac i believe you can have a shop custom make your ac lines and wire up the ac clutch should be good to go.
