The classic irony of the anti soldering brigade is that on the other side of you mega dollar autosport connector its fucking soldered to the board of my $15,000 ECU LOL as it is in every single F1 car! and its all done by hand by a human with a soldering iron
It is totally fine to do it to a wiring harness so long as the joint is then supported against vibration and stresses and strains, this is common sense, glue type heat shrink you will see used by lots of people to reinforce these sodlered joints.
I've even repaired thermocouples and resoldered the wires back on past the Inconel sheilds then siliconed the joint then used simple heat shrink and these last longer than the fancy coiled wired strain reliefes.......... allot of this is common sense and its easy to use cheap and easily available products to ensure you have a reliable wiring solution without resorting to holding up the local 7-11 store to fund your purchse of XYZ dildo race car NASA spec Internet recommended brands.
FFS just look at how planes were wired in WW2 or how race cars won LeMans, they did all of this before XYZ "best practise" was pushed down your throat by layman 'experts' ................ its just pure common sense, problem is in the internet dildo phone youtube age its no longer common
