Engine Harness Connections??

[fixkick]

or we could do ...???
what dont work?
and fix each 1 at a time. (much more easy)
when all works and still lots of connectors, that is normal on all cars made (options never opted)

i do not have the harness pages, as seen in the FSM, physical harness pages.. shows them all and there pig tails , sections.
but do have all schematics . alldata.com has them all too... log in and read.


options. not opted
alarm
DLR
door locks
door windows. elect.
RWAL (rear wheel antilock.
rear washer and wiper. option., (usually 4dr only)
auto aim head lights.
Cruise.
fog lamp option.
defogger.
A/C (1/2 there or all there...???)
electric mirrors
Calif . EGR.
Trailer package.

and more..

not knowing this, makes DISCOVERY very hard.
photo of RPM tag , shows all options. added.

i think fixing things that fail, 1 by 1 is best....

i first look at the engine sensors. all working , present and wired.
and insert the diagnostic jumper DLC and see if the CEL lamp flashes 12s. or not.
