i need a hand, i got the management from a friend who unfortunately cut a cuple wires....

basically i hav a plug for fuel rail, flywheel sensor and top of thermostat, battery lives and coil....
i "think" the 2 inside that are cut (being a red and a black) could be perm live and ignition live?
also hav what looks like 2 wires that would go to a lambda sensor.... if this ecu needs a lambda?

i no its hard to giv me any reply but if anyone uses dunnell then i can load up pics and can show in detail the couple wires i need confirmation with!
so do speak up chaps n chapess's! thanks
