-Do I need a relay between a switch, thats sharing a 10 amp fuse with 5 other switches running to relays, and a starter mounted relay? All the drag car wiring schematics I have seen have a relay between the switch and the starter mounted relay.
-Do I need a relay between the ignition power wire on my tpi ecm and a switch in the configuration I talked about before?
- So far I have fan, water pump, ignition (I'm doing ecm, I'm not sure if that's what ignition would mean), and fuel pump on one toggle switch panel. I have 1 unused toggle, any ideas on what I could use it for?
-I'll search tonight but while I'm typing this, what glue is best for mwhen the center console rubber/vinyl(?) starts seperating from the hard plastic?
Take a look at your max current draw and the rating of the contacts of your switch PLUS 50% . I would expect 15A for the ignition, 0 for the switched ECM, 6 for the each heated O2 sensor, 10 for an electronic transmission, 5 for the TCC of a non-electronic transmission and 15 for the injectors. 0 for the ECM switched because the ECM gets it's power from the unswitched lead. It only senses the switched lead to turn on and off. Your ECM btw switches off many seconds after the switched lead is switched off. If you are including the unswitched power to your ECM add 7A. Note - no, the ECM doesn't require much power. The ECM grounds most of the things it runs. The current runs through the ECM but it is not drawn from the power wire of the ECM.
Ignition is usually considered the power wire that runs to the ICM.
