I was soldering in boost control components on my p75 ecu when i noticed on the backside of the board, in the same area as q20 there were two components/4 legs sloppily bridged/soldered all together. Is it supposed to be like this?

Post a picture of what you are referring to.

So unfortunately I already Desoldered it before I thought that it might be like that for a reason but in the attached picture the screwdriver is pointing to q23 and dm10, all 6 legs were connected in a sloppy puddle of solder before I Desoldered it. The ecu worked fine like that also. My p28 ecu is not like that, is it a non vtec ecu thing maybe?

It sounds like it should not have been that way.

Can you suggest a good place to tap the switched 12v source for the boost solenoid. I am already using the one for the radio for my wideband and the one for the cigarette lighter for my water meth controller. Is there another one you would suggest using?

You should not use the radio as a source for power. Use the empty spots in the under dash fuse box as there should be 1 or 2 that are switched with the ignition switch.

I dont have it ran off of the actual radio, the radio is uninstalled and im using the switched 12v wire that was for the radio. Are you saying I shouldn’t use that wire? If not, what is the reason?

I would recommend running a fuse sub-panel to provide power to all the accessories you're adding (gauges, wideband, boost solenoid, etc.). I'm using a 6 circuit panel and a relay to control when it is powered. This way each gauge, the wideband, and the boost solenoid all have their own fuse that is the correct size.
