Well, almost success. Still have to connect the electrics on the Mico lock.

Gary, what did you hook the low pressure switch up to? the horn relay or a
seperate alarm?

BTW, the brake difference is beyond words, but I'll try as soon as some time
available to update the website.

Heinz--
I could see no use for the alarm feature (same conclusion that Leigh came to
IIRC) so I did not hook it up. I have an added electrical fuse/relay panel
which has both ignition and battery sources with lots of fuse blanks. This is
where I hooked the momentary B+. I can't see where it makes much difference
where you connect as long as it is not switched by the ignition. BTW, I have
left my micro-loc "on" for a week without any leakage; brakes locked tight

Gary,
Alarm aside, the wiring diagram on mine shows a DPST switch, not a momentary
contact. I.e. to keep the lock engaged 12V power is maintained to the
solenoid. Did you install with a latching relay or is it a typo :-) ?

I'll probably put the alarm on a warning light as a 'Brake fluid leakage'
indicator.

If you got the same switch I have (MICO, don't have #), power is needed only
when locking the brake. A momentary contact is all that is needed -- no relay.
To lock the brake, you apply full pedal pressure, then hold the power switch
"on", release brake pedal pressure, then release the "on" switch. The lock
stays locked until brake pedle pressure is heavily applied again (no switching
needed). HTH

I guess I'll find out when I get it wired up.

The switch that was included is an on/off and the label says turn on switch,
apply brake.

To disengage, turn switch off.

Perhaps different model of Mico.

I surely would not want the parking brake to be dependent upon a voltage being
applied to the valve. If that is the kind of valve you have, send it back!

Gary,

Any chance you have a partnumber of the Mico Lockvalve, i.e. number on the
box?

Heinz:

Although my brake lock isn't installed yet, one I got from Leigh is Model
Number 02-620-009 and the label beneath that has: MBL 3 PWS.

Paul,

I just have a date underneath, but it's the same model number.
