I have read that if you change the intake and exhaust manifolds from a USDM engine to the JDM, that you can. Theoretically, they are the same block and head, but US emissions standards require more sensors for a cleaner exhaust. Not quite. The emissions standards in Japan have been higher than the US for many years. Secondly, the head is not drilled for EGR on the JDM engines, nor is the intake manifold, but the engines will run just fine without the EGR systems, and only California emissions model cars have a sensor to turn on the Check Engine Light if the EGR system is removed. The only other changes that would need to be made to run a JDM engine with a USDM harness and ecu is to change the oxygen sensor from the 1 wire unheated JDM sensor to a 4 wire US spec oxygen sensor. The JDM engine will also have a exhaust temp sensor after the primary catalytic converter that is unused on USDM cars, and there is no connector in the USDM harness for it. I have heard it was used for a light on the dash as a warning on righ hand drive JDM vehicles and so is completely useless in a US spec car.

you don't neccesarily need a wiring diagram if the stock plug is still there. when you buy a wiring kit for that specific vehicle the wires will be color coded to match up to the new radio (red to red, yellow to yellow etc). you just connect the wiring harness for your truck to the wiring harness for your deck and plug 'em in. if it's not need a 12v constant, 12v switched, ground, and +/- spekaer wires for each set of speakers.

What is car stereo wiring for 1993 GMC jimmy?

there is a harness that connects the speakers, the stereo and any power (extras bought) in a single bunch. most stereo kits make adapters that fit on the back of an aftermarket stereo so you don't have to cut the harness. however, it is a tight fit behind the stock stereo because of a plastic backing built into the dash. recommend to not cut the harness and find a way to fit it all (adapter, new stereo harness, stock harness) into the space provided.

How do you remove the stock radio from a 1992 Jeep Cherokee and what is the color of the hot wire when you replace your old system with a new one?

To remove the radio, you will have to first remove the dash bezel, which is held in by four Phillips-head screws, two of which are above the instrument cluster, the third is above the cigar lighter and the fourth is above the headlight switch. The bezel also snaps in as well, and you will have to carefully pull it free of the dashboard. If you have tilt steering, you will want to tilt the column down as well. The radio is held in by two screws which have 10mm hex heads. You will have two hot wires. The red one is hot only when the key is in the "on" or "acc" position. That one will actually power the radio. There is also a pink wire which is constantly hot. That wire feeds the memories for the electronic tuning and clock. However, if you still have the stock wiring harness, you will want to buy a wiring harness kit which plugs into the stock wiring harness instead of hacking up the stock harness. These wiring kits are available for under $20 at most major auto parts stores and possibly Wal-Mart, and their wires are labeled (or a schematic comes in the package) for easy connection to the aftermarket radio.
