Marshall Ruskin asked why we don't just use the required plugs to
create a new harness rather than hassling with the spaghetti mess. I
too have thought about this and think its worth considering.
However, as a novice, not too familiar with idendifying the right
plugs, I must admit that having to trace the wires from the computer
to the plug is helping me to identify the correct plugs. On my first
try at identifying the plugs from Kennedy's drawing I made a couple
of mistakes which I corrected as I starting snipping and removing
wires.
The ideal situation would be to have a source for harnesses made to
order. Problem is, I don't think the plugs are standardized for all
years from 90-94. (Kennedy has investigated this some but says he
has not been able to find a supplier of the various plugs.) I was
shipped the wrong harness from a 90 with my 92 engine and the plugs
were different. Harnesses to order would involve a fair bit of
research by a willing vendor. (Not yet on the scene.)
There is a company in Southern California who specializes in high
performance Subaru engines for sandrails, (Leading Edge Performance).
They have some VERY EXCITING performance mods for 2.2L and 2.5L
engines but not CA smog legal.
They make their own wiring harnesses but so far only have them for
the 2.5L which has a single plug at the computer instead of the four
yellow ones (90-94). I've been talking with them making one for my
'92 but they're not sure they want to do it. They charge $400 for
their 2.5L harness...a bit pricey but, for some, worth the time
savings.
