I need to extend some wiring.
In the past ive used resin core solder and heat shrink tubing with electrical tape and wiring loom over it. Is this the correct way? Will it change readings from sensors like the TPS ignition coil because of the rosin core solder? |

A proper splice should add minimal resistance to the circuit. If it was a high current circuit it could be a different issue, but for a sensor circuit, a few extra feet of properly sized wire and a good solder connection should be of little consequence.

Dunno about the TPS cable, but if you encounter any sensor cables with two insulated wires twisted together as a pair (not actually connected together), be sure to continue the twist in your extension.

How many wires do you have to extend? Soldering is a PIA. If you have a lot of wires to extend it would be worth it to buy some good quality crimp connectors and the proper crimping plyers. I have quite a bit of wire shortening to do so I bought the stuff and am just looking for the time and gumption to do it.

I just extended some oxygen sensor wiring with no issues at all. Used rosin-core solder, heat shrink, and then tons of electrical tape to keep it all together. No side effects at all.
I've had no good luck with crimp connections, though I'm sure some are better than others. |

That made all the difference. They have a point on one side that pinches in the middle. Hard to describe. I can't find a pic of what I have. |

For the little bit I need to splice wires, soldering works for me. Once it's done I never worry about it. |

I have quite a bit of wire shortening to do so I bought the stuff and am just looking for the time and gumption to do it. Right now I only have a couple dozen wires to extend for the delteq. I've looked at those mil spec wire crimpers to build some cannon plug terminals and I can't justify the cost. I can see that it would be worth it if/when I decide to rewire everything. But for now it just doesn't seem worth it. Thanks for the input guys. |

I had few crimped wires work loose in the past. Now, if I haveto crimp, I also solder them into the connector.
