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?
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?
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?
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.
