I have a 90 T2.. it doesn't run. It is actually a 87 na that I have changed everything on... I put a 90 jdm turbo motor in it. Changed all the wiring harness'. I can't seem to get it to run... come to think of it the trans harness might be off of a automatic... I don't know if that matters. all the other harness' are t2 harness'. I can get it to turn over but not start. anyway I was thinking about buying the microtech so I can get it to run. what would I need to buy to put it in and get it running?

thank you. pm me please.

 

If you have to ask these questions, then I don't recommend getting a standalone. You need to make the wiring harness basically from scratch, and then there's the tuning...

But to answer your question, the Microtech harness is flying lead. You need to transfer the connectors off your old harness (or better yet, buy new connectors) onto the Microtech harness. Some leads have to be extended, some cut. You need to wire the Microtech into power and ground, and then rewire the stock temperature gauge and alternator (those wires are on the engine harness which you will be discarding). After the car is running, it needs to be properly tuned via a wideband.

 

Where you get new connectors at?

 

Auto parts store. Off the shelf, they generally have injector connectors are standard WeatherPack connectors. In the catalogues, they usually have OEM connectors for almost everything (it just takes hours to find them).

I almost always replace injectors connectors (they get baked), use the existing CAS connector (generally just needs cleaning and lubrication) and existing coil connectors. For any other connections (ie. e-fans, ignition boxes, connection to stock harness) I use WeatherPack.

 

Thanx dood
