I have just finished swapping out a Series 4 Engine, ECU Harness, and ECU for a Series 5 Engine, ECU Harness, and ECU. Everything is done except for the connector for the Chassis Harness into the ECU. I am well aware of the fact that the Chassis Harness from a Series 4 does not plug into the Series 5 ECU, but I have a few questions.
Things to consider:
1. I do not care for emissions at all, therefore NO EMISSIONS.
2. I have done a search on the forum (many times - many different keywords and no go) and have not turned up anything useful.
3. I just want the car running with all accessories functional (PW,PL,AC, HEAT, Etc...)
4. I've hooked up the sensor in the Oil pan by splicing the wires together (there is one more wire left [black] which is for another sensor in the oil pan - Series 4 only - I left that one unhooked.
5. For the series 4 the TPS connector is on the Chassis Harness and Series 5 is on the Engine Harness. I have not spiced them together - YET - only the Series 5 TPS connector on the Engine Harness is hooked up.
Questions:
1. On the engine harness after you have fished it through into the interior there are four connectors at the end. Two are for the ECU (Left and Centre) and two are left (For the series 4: they connect to another connector which I'm guessing is for the rest of the dash harness, and the other goes into a little back device (looks like a some sort of sensor). What are these connectors and do I have to splice them in to get the functionality I want?
2. What are the two sensors in the Series 4 Oil pan compared to the Series 5 and what do I do with the other missing sensor connector for the series 4 chassis harness?
3. For Series 5 the TPS is wired in throught the Engine Harness, but for the method I have chosen to do this swap will I have to splice the additional TPS connector on the Series 4 Chassis Harness? (My guess is no)
4. Now, heres the big one. I know that the very last connector that goes into the Series 5 ECU (RIGHT Side) is different comming from the Series 4 Chassis harness, I have have a cut connector for a Series 5 Chassis Harness which fits into the last socket in the ECU, if I trace and spice in all the required connections, will the car run? (Note: Question is will it run reguardless of some of the interior functions not working like AC).
5. Has anyone been sucessful in Swaping in a Series 5 Engine, Engine Harness, and ECU in the a Series 4 Turbo Rx7?
Please and thank you in advance for the help!!

1. the black thing is either the auxillary fan relay, or the knock control box. the knock box is internal to the ecu on the s5's, so you dont need it.
2. theres the oil level sensor and for the 49 state cars an oil temp switch. the oil temp switch is for the subzero start assist, you dont need that
3 huh? s5 tps is on the engine harness, if you use the s5 engine harness it will just plug in
4. the only things on that plug are the ignition outputs, the s4 has the cas wires there, but the s5 doesnt, so you dont need em anymore
5. yes, its doable

[quote name='error*' date='Apr 6 2005, 07:42 AM']Eh.... I didn't mean the TPS at all... EDIT - TPS = CAS: I mean CAS not TPS. Thanks a lot for your imput. I'll get back and post my results!

yah you just end up with a spare cas wire, its no biggie

UPDATE - Finally got it beast running took 6.5 hours (excluding the engine R&R). I am in the process of a complete detailed outline on the rewiring of getting a Series 5 Turbo Engine, Harness, and ECU running in a Series 4 Turbo Chassis.
I'm still the the process mind you. I've got a hell of an exaust leak (at the turbo - when you gun it it has no power -its almost scary sounds like a blown engine ) and I have yet to wireup the following:
- Factory Boost Gauge
- Factory Temp. Gauge
- Self-Diagnosis Check (Monitor Lamp)
- Malfunction Indicator Light (MIL) Lamp
- Self-Diagnosis Checker (Malfunction Code Number)
- Power Steering (P/S) Pressure Switch (Is there even ones in Series 4?)
So for all the guys who are posting on whether or not they can install a Series 5 engine, harness, and ECU in a Series 4 Chassis. Yes you can, but it is a lot of work. BUT it is about the same as taking the Series 5 block and stripping it down to a short block, transferring all your support hardware from your S4 (with the S4 front cover and oil pan), and then installing it. I think it is even a bit easlier provided you have a step by step color coded, and picture guide. WHICH I PLAN ON POSTING as soon as I have time.
PS. I most thank j9fd3s because with out his feedback I would have just taken the engine out and done it common way (strip engine change to S4 front cover and oil pan - stick on all the S4 support hardware and install). Thanks Man.

hi nice site. this is my first post but i have been keeping up regular with the forum for a while now. Im from the UK.
I am currently swapping out my JDM turbo S4 cabriolet engine for an S5 engine from a coupe donor car.
I have got to the stage where i have converted the cabriolet from an auto to a manual, and the S5 engine is ready to go in. pretty simple stuff actually.
now all thats left is the wiring - it would be a great help if I had this diagram error* was talking about! as i dont have the foggiest nor can i find any info on this last part of the conversion anywhere. I do have the FSM's but they arnt very clear either.
thanks in advance and REgards
