converting my 87 speed dencity to mass air. what do you think of the ford racing brand wiring harness. summitracing.com sells it, part #:FMS-M-12071-C302.
Do you lnow if it is plug and play for an 87?
Is it a good harness?
I'm sure the Ford harness is good quality,
however (and I don't know the price for it)
I bought a very good, complete Interactive
Systems Technologies www.mass-air.com
I think on ebay for about $35.00.
There really isn't that much to it, just
a plug for the mass air meter with wires
and pins, and some extra pins for adding
the fuel pump sensor wire, etc.
