Ecu Wiring/splicing, What Is The Neatest Way?

[Shoujiki]

Hey guys,

I'm at the point now where I want to connect some devices to my ECU. The devices require a splice in connection to the ECU harness (ignition, rpm signal etc).

Now before I go in there and splice in, stripping back the sheath and winding the wire around and soldering, i'm wondering is there a neater way to wire in this sort of stuff without effecting the factory loom? Are there breakout terminals that can go between the ECU connector and the wiring harness connector to provide wiring "terminals" to each output/input? Can you replace the ECU wiring section from a connector at some point along the line?

Thanks guys,

Regards, Kurt.

Apexi do an extension harness that sits between the ECU and the loom. If you really dont want to splice the factory loom then i think this is the best way that i know of.

wish id seen them before i wired in my G4, but then again, once you go aftermarket ECU chances are you will never go back to factory anyway.

I once found some splicing terminals at Dick Smiths (IIRC) that basically create a "T" connection onto any given wire.

(have a look at the 3M catalogue for "3M Female Disconnects - T-Tap Nylon Insulated Self Stripping" - http://multimedia.3m.com/mws/mediawebserver?mwsId=SSSSSufSevTsZxtUnY_vM8tSevUqevTSevTSevTSeSSSSSS--&fn=03_Termnl_KitsTools_v03.pdf)

Thanks for the posts guys!

blind_elk, thanks yeah I've used those before, and probably would use them again if there was no other option. Last time i used them they didn't make much of a mess with the loom so they were a great option.

Since i'll be wanting to run a Nistune at this stage, i'll be only tapping into wires for various devices (Bee*R Limiter and at some stage, an MFD)

gotRICE? - That is exactly what I was after!! Thanks for finding it!

Your welcome.

If you get one, just double check every single wire and that it goes to its corresponding pin on the other end of the harness. I have heard of the odd one being put together wrong and causing headaches.

Although that was those green Hondata harnesses when they first came out.. still, good idea to check.

Will do mate, that's a good bit of advice. Would be a headache to find out there's a crossed wire causing issues.
