OK, anybody who had installed high-z injectors did something like this:

I did my myself. But I did solder wires. According to description SpoolingUp DID NOT. Can anybody tell me the reason? Did I do wrong?

Thanks!

Even the OEM's are switching over to crimp splices for repair instead of solder, things like the airbag ckt's where keeping the correct resistance is crutial are now repaired using crimps and heat shrink.

Reason being excess solder creates can create more resistance in the ckt being repaired, the wires strength can also be weakened when overheated and become brittle.

Did you do it wrong? No, not if you're good with a solder gun.

 

Interesting thread regarding resistance... I use crimps but have never added heatshrink on top of it

 

I use solder sleeves from tyco. I myself will always have some type of solder ,I want a permenant connection

 

Many, if not most, high end racing wiring looms are built with crimps, not soldered...

Solder causes stress in the wires where the joint transitions from "solid" (solder) to wire, where crimps do not have this type of issue. Properly crimped joints are as strong as the wire, and less succeptable to vibration damage...

 

Crimp connections are far better then solder connections when it comes to wiring harnesses.

Provided it's a good style of crimp connector, properly sized, and crimped with the correct tool.

Aircraft wiring is almost all crimped.

 

Anyone have a personal crimping tool they recommend?

 

Depends on what you are crimping.

For "open barrel" style crimps for splices and ECU pins, I've used the hell out of these.

Yup, unfortunately, they also used calibrated crimpers that are about $300 and you need a different one for almost every pin out there. They sure are nice though when doing cannon plugs.

 

Soldering also is more prone to breaking due to vibration than crimp splicing.
