Hello all! I have this long pending project, a Peugeot 604 SL that I at one time upgraded to be the GTi using the Volvo 760 B28E engine and eventually installed the Peugeot 605 SVi ZP engine. I had to get some parts off the ZP engine and replace with those of the ZM engine so that it's a straight fit in the car. These were the water pump, crank pulley from a Renault 25 that has a serpentine belt section and an ordinary belt section to drive the power steering pump. Also, I changed the bottom sump area so that the engine mounts fit as well as have the bell housing bolt onto the engine. I had to rectify the throttle intake body to face to the side so that it could fit in the engine bay via cutting and welding it. Initially it was facing upwards towards the windscreen creating an interference with the firewall. I replaced the restrictive Peugeot 604 exhaust manifolds with two from a Volvo 760. They are more free flow and allow easier starter motor as well as alternator installation. I also opted to use the Bosch starter motor off the Volvo in preference to the Ducellier one as it has more torque, less noisy, easily available. Now, am left to figure out the ECU pin outs for the ECU I have { part number S101700101 G} which I would appreciate any links or diagrams for it so that I can recreate the cut up wiring harness I have. Attached are a few pics of the project.

Hi everyone! Just came across this post as I was searching for a wiring diagram for the E.C.U pinouts for the ZP J engine as I have a similar project am working on, A 1976 Peugeot 604 which had a smoking ZM 140 engine. That's the odd fire, 2.8 Liter with Bosch Mechanical fuel injection. I took the aluminum section of the ZM sump and swooped it with the ZP J engine so that the engine bolts onto the bell housing straight away and the engine mounts bolt onto the cross member straight away. For the exhausts, I used the existing exhausts manifold which was also a straight fit. The exhaust manifolds are the same ones used in the 505 V6, Volvos 264 /760. The ones of the older 604's are restrictive to exhaust gas flow as well as starter motor removal and installation. As for the cooling system, I swooped the ZP J water pump with the one from the ZM 140/ZN 3J so that the engine could still run with the engine driven fan-i like the sound of it. The radiator is off a Volvo 264-the Peugeot ones are a little bit tiny and let the car run hotter than should be in many tropical areas. The top cover on left side of the engine when facing the engine will be replaced with that from the ZM/ZN engine as it has air con mounts that are interfering with the brake booster. The challenge ahead now is to find a ZP J efi wiring harness or diagram showing the ECU pinouts I rebuild mine as its badly damaged. Anyone with a diagram perhaps? Much appreciated!
