Is there a how to anywhere on fitting S15 coilpacks onto an S14 loom?
Thanks.
thought they have the same connector? surely its just a case of bypassing the ptu and plugging in the s15 coils?
ptu bypass is easy and theres a few ways of doing it. can either gut and bypass an old ptu internally, chop the connectors and solder, or buy a plug in bypass from wiring specialities

The + and - are the opposite way around on the S15 coils IIRC
Looks straightforward enough looking at the patch loom from there, Norfy...http://www.wiringspecialties.com/s13...n-chip-bypass/
that looks like a good option tbh, had a buddy recently get one over and the quality looks good.
Strange i just plugged my S15 coils stright into my S14 no problems at all. Although I did have to use a few washers to make up the gap on the lock down bolt as the coils were slightly too long.

Had to flip two wires at the connector, and bypass ptu.
Pretty easy to move the wires in the connector.
If looking strait at the connector (terminal side), the pins should be:
S13/S14 - [ - + Sig ]
S15 - [ + - Sig ]
