Hi guys I was wondering how did you connect the wires that are supposed to have 12V running to them? I want to make this look as neat as possible

This is pretty much a custom install into a race car so I don't have all the factory wire harness crap that is usually in the stock car. Thanks

On the Sport and Elite long flying lead harness, run the red/blue wire to the rear iron area, cut it there and splice down to 20g wires for each individual injector. Use a non-insulated crimp butt splice and cover with double wall, glue lined heat shrink. Process will be the same with a Sprint, but you'll need to build your own power circuit with a fuse and relay.

Is it ok to solder the wires and then heat shrink or is the butt splice better. When I pulled the stock harness out of the car it looked like the factory just crimped the wires together like on the ground wires etc. I believe they did the same with the injector wires. I was just thinking solder would be better.

Age old debate. I crimp.

When the solider penetrates into the wire it gets brittle and is prone to breaking/failing. A proper non solider crimp with adhesive lined shrink will provide the best splice with stain relief to pretty much eliminate any chance of failure.

What he said. Now we wait for the internet to strike and tell us how wrong we are.

i agree with the theory that crimping is better, but i'm really good at soldering, and really terrible at crimping; even with the right tool, that for ME soldering is the better choice. i know on the internet theory > practical application, but if our lives depended on my crimping skills we'd be dead.

i was thinking the same thing today. I hate how janky going from 1 wire down to 4 looks.
