mirae1 Posted April 11, 2006 Share Posted April 11, 2006 Reading the forum I find that most of you need to type slow so I can understand...Here is my issue. I pulled an engine from an 86 coupe and stuffed it into an 88 wagon. Both engines are MPFI 1.8s with turbos. The Engine was already out of the GL when I got it. Went in easier then any car I've ever done before. Trouble comes from the wire harness. The primary one accross the top was easy enough I just pull the one of the intake that was lying in the back of the car, changed out the Throttle position sensor and all was good. My touble comes from the one that runs along the back of the engine that connects to the Distributer. The one from the 88 was gone...It appears the 88 crank position sensor plugs into the primary harness over the intake..The 86 pluged into the secondary one that feed the distributor. Where should I plug it in and where do the leads in the 86 harness go... The engine will start now if I pour gas down the intake but the injectors are not firing..I assume it is from the Crank sensor. Link to comment Share on other sites More sharing options...
MilesFox Posted April 11, 2006 Share Posted April 11, 2006 86 is the only year where the connectors were different you can swap the wiring harness off the intakes, or just swap the whole intake as well if you notice the 86's intake boot has a hose between the airbox and itself, where the 88 does not. you can keep this boot and airbox or swap use the boot and airbox fro the 88 if the connector on the distributor is different, you can swap the pigtail f ro it or the whole disty itself as far as the individual coponents that the connectors may differ, they all work the same Link to comment Share on other sites More sharing options...
mirae1 Posted April 11, 2006 Author Share Posted April 11, 2006 Thanks for the input....I have swapped the harness off of the intake but I do not have the harness from the distributer for the 88 so am using the one from the 86. My only question left is on the Crank Position sensor. The 86 plugs into the same harness as the distributor and the 88 plugs into the harness on the intake. So I have two places to plug into it. I am assuming I need to plug into the one on the intake as that is the one from the 88 which is the computer I am using. But where do the wires go on the other harness and if I leave them open will it create an issue. also will a sub run with the CRank Position sensor disconnected???

MilesFox Posted April 12, 2006 Share Posted April 12, 2006 does your distributor have a round white(or black) connector? this would be the 86 styledisty connector. the 87 and upwould have a square connector i would believe, as it would be on 87 and later, the disty plugs into the harness under the oil, not on the intake you can improvise a connection and match toe color of wires, or try to find an 87 or later disty, or at least the wire from one describe this extra connector on the intake, what color/shape is it and where located?

mirae1 Posted April 12, 2006 Author Share Posted April 12, 2006 Well I thank I have it figuered out. I found an 87 turbo parked at a local apartment complex and stopped and got permission to look under the hood. When I moved the engine from the 86 into the 88 i left everything attatched. The harness that went accross the intake did not match up so I swapped it out along with a couple of sensors so everthing matched up good. There was a second harness that went along the back of the engine: from the coil to the Distributer then to sensor behind the intake down on the block(I'm assumming this is the Crank Sensor) and finally plugged in on the right fender. The plug was there and matched with the harness from the 86 so I just plugged it in. Now after looking at the 87 I learned that my 88 most likely did not have this second harnes. I dug around under the left fender and found the four prong plug that went to the 88 distributer. I am going to put the 88 distrubuter onto the engine and pull the other harness. I'm assuming that the plug on the right fender is an alternate harness for different engine configurations. Thanks for the intrest and help:) Link to comment Share on other sites More sharing options...
