The only difference between the 86-88 auto Harnesses would be one connector for the oil pressure sensor and one for the TC lockup function. The stick harness would have only one different connector . Problem easily solved by using the 88 oil pressure sender. The ECM's are identical except for the chip. On the auto the TC lockup function is included and one the stick the shift light function is included. Easily solved by plugging in the stick or auto chip. ------------------

It also uses different connections at the alternator.
Also be aware that some of the 88 harnesses had a revised connector for the injector harness. Most of them have the same flat connector that the earlier harnesses used, but a few of them used a more square connector.
Automatic harnesses are quite different from the manual harness. In addition to the torque converter lockup wiring, the auto harness also has the connector for the gear selector, which incorporates the reverse lights and the P/N switch. The heavy starter wire also appears in a different place in the C500.[This message has been edited by Raydar (edited 07-16-2023).]
