Crimping vs. Soldering

Here's what I do.... I use the B/Y wire from the main fuse block, EGI fuse I BELIEVE as the turn on for the relay thaty powers the ECU.... It's also used as the turn on for the radio, the GPS, Sirius etc etc etc etc... Which ever ciruit you use, it needs to be hot when cranking. Wire the relay directly to the bat through a breaker/fuse.

For the ignition system, injectors, fuel pump etc, I use the Fuel Pump Relay option in the Motec. It's adjustable for time on, delay, whatever. This output triggers the relays that turn on power for the injectors, ignition, solenoids, etc. Each has their own fuse and relay.

lol, you didn't answer the question though. I have 4 coils but only 1 12V wire. Should I use op-amp circuits to ensure each of the 4 wires coming from the op-amp have the same current and voltage to the coils, or should I just use a junction box which ensures equal voltage but current is different? (It's on topic because Op-Amp I would solder in the wires, junction is a 'crimp')
