91 motor+tranny into 88?? HELP

[devon527]

Im doing my motor swap right now, so far so good but there is a extra set of wires on the transmission where I believe the backup sensor is? There is only one in the 91 tranny but two plugs in my 88 tranny. Thanks

[devon527]

Okay here are some pics, oh and by the way that plug on the right is the one out of the new motor, it was cut when I got it.



And here's the new motor and tranny, it only has one plug?

[gestiva]

one might be a 4speed? and the other a 5speed?

[devon527]

They are, my 88 was a 4 speed and the new one is a 5 speed, but I dont know what the extra plug is for?

[Festiva Time]

The upper one is the Reverse Light Switch And the lower right is the Park/Neutral Switch.

On my '90, THe wires are broken too, and the car runs fine without.

[devon527]

So the new tranny only has the reverse light switch on it? Thats all I need, If thats the case then why would my 88 have a park/neutral switch if its a 4-speed?

i removed the sensor from the trans.........one wire was broke off where it enters the plastic housing and the other only had a few strands left holding it to the sensor so i cut them off flush to the plastic........i used about a 1/16" drill to go into the plastic right next to each of the 2 wire stubs that were showing, 3/8" deep......i had [2] 1" long stainless screws a little over 1/16" dia.,..........i screwed them into the holes where they meshed into the wire stubs, then cut the heads off with a dremel leaving 1/2" showing.........tested it with a multimeter which showed a closed circuit when i pushed in the button on the sensor........went to the harness and crimped on 2 pushon female connectors adjusted for a tight fit on the 2 screw ends..........hooked it all up and it works..........

Hook up

That is all I did. I think, the switch had a purpose in another car but is not used in the Festiva.

I put a rebuild '88 motor/ 5-sp manual into my '90 festiva [after swapping the fuel injection related items.

Okay cool thanks I appreciate all the help. Now im stuck, I planned on doing the whole motor swap this weekend but I was dumb and didnt think ahead to get a new intake gasket for the carb after I swapped it... Now I'm waiting till Tuesday just to get it So bummed

[1988festivazoom]

i never hooked mine up so i have no reverse lights but dosent bother me bc i live in town and never need them.

Okay I have a new problem, when we pulled the motor and tranny out, my friend decided to just cut the passenger side CV axle boot right after it comes out of the tranny and now I cant get it to come out, any suggestions??

[villageidiot]

prybars one from the top one from the bottom, give an even firm pry

[FestYboy]

what a great friend you have there....
you need a prybar and posssibly a hammer (mini sledge)

try to pry the axle out at first, but if that doesn't work (and it often times doesn't) place the pry bar against the axle and then pop the SIDE of the bar with the hammer and that shoud get it out.

[crazyrog17]

Do the prybar/hammer trick. Prying on the transmission housing could crack it. Put strain on that crack and there you have a shattered tranny. At 70mph? No thanks.

Okay thanks guys, I will try tomorrow night after work, my dad said he might give it a try too. I appreciate all the help
