Top of my head, 12v+ = Red Ign 1 = Black or BLACK/ blue ign 2 = BLACK / YELLOW Starter = RED / black Acc =Thin red or yellow/red Use a 556U and set it up for european cars, don't use the loop All above from ingition switch, remove at least top cowling (PITA) Door locks neg in plug in DKP from driver's door door contacts, think BROWN / white driver and pass kick panels diode together. trunk, go to trunk, hood, might need a switch unless there's an existing, either front rail or hood lock mech (microswitch mounted there) Lock wire, extend time for comfort close Tach, go to one of the odd coloured injectors (one wire will be the same on all 4 injectors, don't use this) If you have a factory alarm, disconnect the folowing:- Indicators (BLACK/ green and black white), horn, unltrasonics. It will trigger otherwise when you remote start. If there is a factory alarm, you can also pick up door , poss hood and trunk contacts there

Ignore the thin blue and thin grey, don't know what the blue does but the grey feeds the turn lever for the parking lights and it shuts down with ignition. Thick reds are 12V+ Input. Thick BLACK/ red look again and one (75) is the starter and it's RED / BLACK. The black red is 2nd ignition. If I'm wrong and they are both the same colour, one will go live with ignition, dump whilst cranking then go live again with engine run. That's your 2n. ignition. The other will go hot (i.e. 12v+) when you turn the key to the start position. Thick black is 1st ignition. BROWN / red is ACC. Whilst you've removed the cowling, see if there's an antenna around the ignition switch cylinder with two thin wires leading to it. If so you have a transponder and you will need a transponder by-pass. The best unit for that vehicle is the DEI 556U set up Euro fashion without the antenna loop. The numbers you gave after the wires are DIn/ISO standard nomenclature. The coil:- if there is one will be mounted to the rear vertical engine bulkhead, driver's side.,use the terminal (I assume for tach) that isn't marked 15 or +. If no coil you will have to go to an injector plug. There are 4, each with two wires. One colour is common to all, don't use it, use any of the others.
