joeparv,
I understand you are upset, but try to look at this situation from the outside, looking in, instead of from the inside, looking out.
I know your threads have been merged, so the chronology might be off, but in reading your thread, these are the reasons why I question your abilities as a "professional" upfitter:
You mention you have done installations on 45 vehicles. I'm sure some of those installs have been on CVPIs. However, it appears as if you are having the majority of your difficulty in dealing with how to install headlight flashers, one of the most basic types of emergency equipment. Almost every emergency vehicle has headlight flashers. You are also having difficulty identifying the different types of wiring harnesses that are underneath a CVPI. You are unable to differentiate between factory wiring harnesses, fuse boxes, ashtray lights, Arrowstik harnesses, and other wires that are under there. A professional would definitely know his way around the bottom of the dash. That's where almost all the wires would end up for the controllers of all those other cars you've hooked up strobes, lightbars, and sirens for.
When "unlisted" suggested you have someone do the install for you, you replied that you knew how to do it, but you were just asking where wires go to, and where "what goes to what." If you don't know where the wires go, then you don't know how to install whatever it is you need to install.
Some of the questions you ask about other emergency equipment also raise some questions about your skills as an installer. You ask what where to install LED HAWs in taillights, you ask what the best grille lights are for a certain application, and you asked "what the hell is a" Motorola Astro Spectra W9. You also asked for help in identifying wiring harnesses that were in the trunk of a CVPI, how to retrofit newer all-red taillights on a CVPI that took the red/amber ones, and how to clean out the inside of a headlight assembly. You also have difficulty trying to figure out how to make the horn work on one of your CVPIs. I would think someone who has done installs on dozens of police cars would know what most of these things are, or what equipment would be better for each application. Even after you were told what those wiring harnesses in the trunk were, you still couldn't tell if they were for a radio or for a siren. That also leads me to believe you don't really read the answers that members have given you.
Then there was a section of your thread where you were having difficulty troubleshooting some strobe power supplies. You mentioned you have done strobe installs on some of the projects you've worked on. You then had questions on amperage/wattage. These are electrical questions that every installer should know. If you use the wrong fuse, or the wrong gauge wire, the emergency equipment won't work properly. This also leads me to believe you don't have that much experience with the wiring, as you still kept bringing up questions about splicing wires and joining wires with other wires. Electrical and wiring skills are critical when installing emergency equipment in vehicles.
All that said, the way your questions are asked also doesn't help. When you use long run-on sentences, bad grammar, and end almost every question or statement with "LOL," or, "what a pain in the ass this is," it makes it seem as if you're not really taking the help you're being offered seriously. You have gotten help from a whole lot of people on the board, many of them are professional upfitters. I would probably get defensive and upset if someone questioned my abilities, also. I think you really need to take a step back and try to watch other installers work if you want to consider yourself a professional. I don't know you personally. I'm not trying to attack your character. All I'm saying is I think you have a long way to go to consider yourself a professional upfitter.
