MJ20 Posted August 27, 2007 Share Posted August 27, 2007 I have a ’97 motor and head with all the renix stuff in my mj. I began going through everything the mechanic did in the swap for the po and there’s some disconnected stuff and some other stuff I can’t find in the fsm and my xj doesn’t have it. Here's some pics. Along the fender next to the air filter is an actuator. What is it? The ’97 head doesn’t have the temp sensor so I have a disconnected sensor wire. So I don’t have an idiot light? The blue vac line doesn’t have anything to connect to. Below the other colored lines all go to a vac manifold. Is this a breather or vac? The ‘97 ho t-stat housing has a temp sensor and the connector was cut off and extended to a connector coming out of a wire loom underneath next to the motor. Is that the computer control? I pulled the two wires up for clarity. Link to comment Share on other sites More sharing options...
Oizarod115 Posted August 27, 2007 Share Posted August 27, 2007 hey man, i just took you like 10 pics of my engine compartment and I'm workin on getting them up for ya. Link to comment Share on other sites More sharing options...
DirtyComanche Posted August 27, 2007 Share Posted August 27, 2007 AFAIK, the t-stat located temp sensor is for the gauge, same as the one in the head on a renix motor. There should be another sensor in the block for the EFI. But I don't know much about the HO motors. Link to comment Share on other sites More sharing options...
Oizarod115 Posted August 27, 2007 Share Posted August 27, 2007 this should be the coolant temperature sensor for the ECU (drivers side of motor, below intake/exhaust manifolds. this is what my PO did for the temp gauge: here you can make out that blue vacuum line which is plugged the same way on my truck miscellaneous vacuum and throttle body area: other vacuum by drivers fender, please ignore my hack-looking relay (for the dual electric fans) Link to comment Share on other sites More sharing options...
Oizarod115 Posted August 27, 2007 Share Posted August 27, 2007 more vacuum junk over by the heater core heading down to the axle disconnect and other stuff. Link to comment Share on other sites More sharing options...
Motion Offroad Posted August 27, 2007 Share Posted August 27, 2007 The blue vac line doesn’t have anything to connect to. Below the other colored lines all go to a vac manifold. Is this a breather or vac? This is part of the CAD setup. The ‘97 ho t-stat housing has a temp sensor and the connector was cut off and extended to a connector coming out of a wire loom underneath next to the motor. Is that the computer control? I pulled the two wires up for clarity. The HO has the thermo switch for the electric fan on the t-stat housing. The Renix setup had it on the radiator. Depending on if your radiator/cooling system was converted to the open system would help determine what exactly the wires are going to. Link to comment Share on other sites More sharing options...
JeepcoMJ Posted August 27, 2007 Share Posted August 27, 2007 are you sure that's an actuator? it looks like a vacuum reservoir...if there are wires leading to it though, I bet that the cable coming out of the end goes to your throttle body. that would be a cruise control servo for an aftermarket cruise system.

MJ20 Posted August 27, 2007 Author Share Posted August 27, 2007 Thanks for the pics. The vac lines pic look like mine except for the big black part on yours has large tubes extending out from the large orfice and mine has a broken one on one side and nothing on the other. Where do those lines go? I will look for that sensor down below in your pic tomorrow but that is where the extended lines are heading. I have the sensor in the rad and it is connected. It still has the closed system. The fsm shows the cad vac system with a breather that must be the blue line. I guess it doesn’t connect to anything. The actuator pic shows a ball chain with a round connector at the tag end of the cable coming out of the big black thing (actuator). It sure looks like it would connect to the throttle body linkage somehow. I have the stock renix linkage going to the stock throttle body. This is a sportruck basic model with no crusie control but that’s what it looks like or maybe it closes the throttle body when the engine is shut off. I don't know it's not hooked up. .

JeepcoMJ Posted August 27, 2007 Share Posted August 27, 2007 it's part of an aftermarket cruise system. guaranteed. Link to comment Share on other sites More sharing options...
MJ20 Posted August 27, 2007 Author Share Posted August 27, 2007 I have to agree it looks like it’s for cruise. There are no other cruise components inside or out and the turn/wiper control looks like original equipment. Link to comment Share on other sites More sharing options...
MJ20 Posted August 28, 2007 Author Share Posted August 28, 2007 It looks like a renix knock sensor is installed where the temp sensor would be on a ’97 ho motor. The temp sensor in the ho t-stat then controls the ecu since it has been spliced from up above to the connector down below for the ecu temp sensor according to the fsm. The third connector is the o2 sensor. Does anyone see a problem with that? Now I don’t know what I will do for the open cooling swap since I thought I would use an ho t-stat temp sensor instead of the rad sensor. Link to comment Share on other sites More sharing options...
