badazzelanore Posted July 22, 2014 Share Posted July 22, 2014 Where should these two be connected and what are they too? 1987 I4. Link to comment Share on other sites More sharing options...
yxmj Posted July 22, 2014 Share Posted July 22, 2014 Just a guess on one.... The square one with the green rubber insulator looks like it should be pluged in to the TB or manifold.....check there to see if there is an open receptical.....again just a guess.

conker Posted July 22, 2014 Share Posted July 22, 2014 the square one with 4 male prongs on it looks to be the tps as yxmj said; should be a female connector on your throttle body for it to connect to. I think that the flat connector is for the Crankshaft position sensor, the other end of that should be somewhere on the fuel rail near the firewall iirc.

1989 Eliminator Posted July 22, 2014 Share Posted July 22, 2014 The both look like they go to the TPS. The TPS has two connectors for it. The square connector is for the transmission side of the TPS and the straight three prong connector is for the engine ECU side of the TPS. That is what it looks like to me.

88whitemanche Posted July 22, 2014 Share Posted July 22, 2014 The bottom one in the pic is for the automatic transmission if it was equipped with one....the top one seems to be missing a connection either from the tb/injector wires or to the idle speed motor....

I do not think the injector wire connections look like that and the idle speed motor is a male connector not a female. At least on my 89 renix straight six. I am putting my money on that they both go to the TPS Link to comment Share on other sites More sharing options...
