s13 vs s14 wire harness

[jc240sx90]

i was wondering whats the difference from an s13 sr20det compared to an s14 sr20det wire harness conversion from a ka and is the difference big?

The S14 carries ABS, wipers, and ECU relay on the engine harness whereas the S13 carries these things on the body harness.

There are also slight differences in the engine sensors on each.

It's a big difference. Even if you had a lot of experience doing swaps you'll still have to spend some time do it properly. Anybody who says differently are either reckless and/or doesn't know what they're doing.

Basically S14 anything will be difficult. S13 anything is fairly simple.

I still see people botching S13 SR into S13 swaps so who knows. On the engine harness, there is one wire under the dash and 7 near the battery. You do not need to modify anything else on the engine harness. It's amazing how people still get it wrong.
