Installing DRL's in a '90 Burb

Well I've had this GM GOODWRENCH Daytime running light module for about 31/2 years now. and am finally getting around to utilizing it. It's a discontinued part that is still in stock at a few dealerships around the states. Part number is 12370131 if anyone's interested in getting one as well just ask your local dealer to do a dealer to dealer search for it.
Basically what this does is it turns on your low beams with a reduced voltage of around 8-10 volts when the ignition key is turned on and when you turn on your headlights, it cuts off and you get full power to your headlights.
However.....A couple of years ago I installed H.I.D. headlights thusly rendering my usage of this module a no go because there was no way I could install this between the H.I.D. controller/ignitor and the bulbs themselves because of the high voltage output of the controller/ignitor. Nor would it work putting it before the C/I without risking doing damage to it.

Plus.... I.......lost the instructions for it.


Here's a pic of it.


I found some 8" wideX 1" tall switchback L.E.D. style DRL's on EBAY that are a simple 3 wire hook up (GROUND DRL AND TURN) Basically when hooked up, they will be white until you activate the turn signal then they will flash back and forth from white to amber.


Testing them with a nine volt battery...



After getting these I found thet they were small enough to fit in my front turn signal housings with little modifications to the housing itself. So I decided to install these and hook them up to the DRL MODULE mentioned above... One problem though, Still no wiring instructions for the module.
Well as luck would have it, a dealership up in Fairbanks happened to have 9 of these modules in stock and after a quick call to them, they were kind enough to fax the installation instructions to me. THANK YOU AURORA MOTORS!!!
