toyota cressida, locks rest at 12v

so i did a four door actuator replacement setup in this vehicle last week, the car is about twenty years old or so, anyway, i swapped out the factory relays and used aftermarket ones for the door locks, as the customer complained about having issues with the original relays, what i noticed is, that the actuator wires originally rested at twelve, and the ground was switched on the legs for activation, it's the first time i've seen this, so i just wanted to find out this.

when the actuators are at rest once the polarity on both legs are the same, is this ok, or will the rest at twelve cause problems as opposed to the rest at ground, i know that the rest at twelve would be the easier prey for problems, as if any one of the leg wires were to short to ground and backfeed to the other actuator legs it would cause system failure as in this instance, where all the actuators froze in the unlock position.

Reversal rest at positive is a bit more dangerous than a reversal rest at ground setup.  It does not appear to be a problem for the car manufacturers because the way they run wires through the vehicles.  I have never seen a factory harness or component short or ground out without any outside help.  All of their harnesses are very well insulated or routed where nothing will get to them.  The outside help is the occasional installer driving a screw through or pinching a wire with a door sill. 

my thoughts exactly as regards to an installer having helped the wire piching, he saaid to me before i started work on the car, that a mechanic, did the door locks for him before he sorted the help of technicians

Darren, I've never seen a car where the lock motor wires rested at 12volts+. It is dangerous for the reasons you stated, also Craig, re harness routing, you would eat your words if you had to work on a French or Italian car, how many door equipment  failures have we found because of a corroded or broken cable on a Peugeot and that's with molex connnectors. Incidentally the Japanese still use rubber grommets and sleeving and I've never had a Japanese vehicle with that sort of problem.

it's my first time too howie, also, i've had a few problems with broken wires on the japs vehicles, but in four years, they're really insignificant numbers

i have a whole library of pics of stupid "crap" turned out by GM, Ford and Chrysler over the years. GM for so many years had the dumbest wiring/routing situations until they wized up and started to copy the Japs and Koreans. and remember the worthless rinky-dink connectors Ford used for years? they are like the same connectors used to hook up a U-haul trailer to your truck. and they even used them under the hood! and as far as im concerned, GM hasnt really gotten too much better and still churns out crap! look at this one if you havent already.

There is a huge difference between a short and an open.  I never said any thing about the quality of their connectors.
