ECM Questions

[GRUMPYNOMO at aol.com]

Well I know nothing about Jeeps but pin-out questions seem to have some
similarity with Jags an LRs so here goes on some of them:
-5v on a Jag is stable supply for airflow and throttle pot
-4 IAC pins because there are 2 circuits and once activated (which results in
a given degree of rotation no matter how long the pulse) you must activate the
other circuit or the first circuit with reverse polarity.  So 4 is the min
pins to do that
-The coil pin on the LR is the only way it knows when to squirt fuel.  There
is no crank sensor on that LH Jetronic setup
