I have '97 Honda Civic 1.4iS (D14A4 engine, P3Y OBD2 ECU). 'New' engine is B16A2, OBD1, P30 ECU. Problem: My OBD2 ECU has weird pinout. Between other things, fires injectors in pairs, has only 2 connectors, which resemble OBD1 type, but are OBD2... etc, etc. So.. I cannot use OBD2->OBD1 converter, etc. Problem2: I live in Croatia (Europe), and belive it or not.. but 'regular' OBD2 harness, that most of you use. Soo... what to do? Simple: use OBD1 wire harness! Is it simple.. well.. so-so.. I used OBD1 wire harness and OBD1 fuse boxes (underhood and underdash). Result: talk about hybrid - '97 hatchback (originally OBD2) with OBD1 engine/ECU, and mix of OBD1/OBD2 harnesses. This weekend finally connected all wires! Only thing that doesn't work now are: A/C (still need to connect wires in front for it), rear fog light (brigt red lamp) and clock on dashboard. Everything else works!!! I still need to fix cables in place now, but that is just 'cosmetic' stuff. Another hting I still miss is rear engine mount, which I should get this week (untill than, car will stay in garage). Anyway, here are few pics! Yay! Before (turbocharged B14A4): And now (engine, work this week on wires, still need to fix those wires in front): One thing tho... when is VTEC supposed to engage on B16A2? By tach it seems just a tad under 6000rpm... is that OK, or is my tach somewhat off?
