Hi chaggitto, welcome to the club
Is a good question "Find the 5 wires needed to run the engine and connect them to the 1200 wiring system"
Most guys totally re-do the wiring system, often purchasing a new SR swap harness. However it is not necessary to start from scratch. If you got the SR engine/ECU harness from a Silvia or other SR donor car, you can patch it into the existing 1200 harness (wires are STARTER, IGN, 12V, GROUND/EARTH). The 5th wire is FUEL PUMP wire from the SR20 harness
Follow the Wiring link in the SR engine swap article. There are many wires in the SR engine harness, but you only need to identify a few of them to connect up. Use severals relays and new fuses. It's a chore but you'll have OEM EFI -- power and economy both with awesome smoothness. Many of the DIY guys use icehouse's Can/AM relay module to make it easier -- with built-in safety
1200 harness -- see Wiring
* STARTER black/yellow wire
* IGN black/white wire (goes to coil)
* 12V from Fusible Link
* GROUND/EARTH black wire/negative battery cable
All these wires are on the back of the Ignition Switch, and also go out into the engine bay. See Wiring#Ignition Switch

Got a pic of you 1200 camioneta?
