My first Question Hello, I've been reading ALOT of info on doing a 5.3 swap. I'm looking at putting one in a 1985 K5 Blazer to replace the tired TBI350 that was originally swapped in.
My question is, I purchased a JY motor with all the acc and wiring harness and ecm. How ever I did not get the under hood fuse block assembly. Is this going to cause a problem when trying to modify the harness? I hate wiring with a passion and I'm tempeted just to either buy a harness or just pay someone to modify the one I have. What would be my safest/quickest route?
This truck is not a Daily Driver it is a play toy but it's that time of year to be rock crawling so I'd like to get it done in a reasonable time frame. Thanks for the info.

You should be able to create a standalone harnless with a new fuse box set up. I usually use a Painless 7 circuit Aux Fuse setup. That usually is enoough for a basic setup. If you need more circuits, the setup is expandable by adding another 4 circuit block on.
I then setup a another fuse and relay setup for the Elecrtical Fan if your using them.

If your not good with wiring and can not find anyone local to help, you can look up one of the sponsor vendors to convert your factory harnless or buy a new custom one. But it is a good thing to learn about the EFI and wiring, it usually takes a few hours for the 1st timers, just need to read the FAQ and get the pin out of your year/model harness.
