Module, Ignition Control, for 90~95 ZR-1 LT5. One (1) Ignition Control Module is required per engine.

NOTE: The first 500 1990 models (see last 4 digits of the VIN) used DIS Module PN 1103747 in conjunction with a "spacer" under the Crankshaft Position Sensor.  When using DIS Module PN 1103841, the "spacer" must be removed for proper operation.  DIS Module PN 1103747 is obsolete.

NOTE: This is a NEW, GM OEM part. When our inventory of this part is exhausted, it is extremely unlikely that we will ever be able to offer this item again. 

 MUST READ, TERMS OF PURCHASE: All sales are final. Please do not purchase this part to "test" your problem diagnosis. We cannot accept returns for any reason.  We regret the necessity of this requirement, which is due entirely to part rarity and demand plus the fact that it is an electronic component which can be damaged by improper handling.
