I've been looking for the correct Code 3 siren for my SSP for almost 3 years now with no luck. The only difference between a new Code 3 V-CON and a late 80's vintage that was in my car is the stupid plug-in mic, the new ones are fixed in place, a minor detail that was bugging the crap out of me! So, first I got a new V-CON, then I came across an old early 80's Code 3 V-CON without the light controls that was trashed just for the needed plug, then I got an NOS correct plug-in mic from ebay. Next I took everything apart and hooked the old style mic to the new siren and I'm now good to go!

My new "old" siren to be mounted soon:
I also got a brand new late 80's vintage NOS Code 3 LP6000 lightbar that I'll be mounting to replace the current bar when I do the siren.
