Default 87 xjs engine harness for 90 xjs

Will an 87 xjs 5.3 engine harness match with my 90 xjs 5.3. Just bought a 90 xjs barn find and all harnesses under the hood are damaged.

This cleaned up really well and I would love to see it running soon

Most of it will probably be different. Sensor cluster might be same but 87/90 had different ignition and I believe 87' had the 6cu ecu maybe different wiring there to...Im not pulling my cars ecu to compare and confirm.

if you need wiring theres suppliers in UK/US
